By Kim Ronan, LCSW, MPH, CST | AASECT Certified Sex Therapist | Beverly Hills, CA | About Kim
Let me guess, you’re lying in bed next to your partner, and something feels…off. As a couples and sex therapist in Los Angeles, I work with people in exactly this moment: the nighttime is quieter now, the butterflies have settled, and a quiet voice is asking, ‘Is this the beginning of the end?’
If that’s you, you’re in good company.
As a sex therapist, I’ve worked with so many couples who panic when the honeymoon phase ends. They come in worried they’re falling out of love, afraid they’ve made a mistake, or convinced that something is broken.
But what if I told you that this shift is completely normal and even healthy?
The honeymoon phase ending is one of the most disorienting transitions in a relationship. And the fear of falling out of love is one of the most common things I hear from couples sitting across from me in my Beverly Hills office.
Let’s break down what really happens after the honeymoon ends, why doubt and conflict often signal growth, and how understanding the stages of relationships can help you stay connected even when things stop feeling “perfect.”
What Is the Honeymoon Phase, Really?
The honeymoon phase is the early stage of a relationship, usually lasting anywhere from a few months to a couple of years. During this time, your brain is flooded with feel-good neurochemicals like dopamine and oxytocin. The Gottman Institute’s research confirms that while this neurochemical rush of early love is very real, it isn’t what determines the strength of a long-term relationship.
You see the best in each other. You’re more generous. You brush off red flags. You prioritize connection. And sex? Often hot, frequent, and effortless.
It’s designed to bring you together, not to last forever.
And here’s where many couples get tripped up: when that intensity fades, they assume love is fading too.
What Really Happens When the Honeymoon Phase Ends
Once the initial rush calms down, your relationship starts to shift. You stop idealizing each other. Your nervous systems settle. Real life kicks in. And suddenly, you’re not just falling in love, you’re trying to build something.
This is where the real work begins.
You start to notice your differences. Conflicts pop up. You realize your partner has annoying habits or baggage (just like you). Intimacy might slow down or feel less automatic.
But none of this means your relationship is broken. It means it’s moving into a new phase; one that requires more intention, more communication, and more emotional honesty.
The Stages of Relationships in the Developmental Model
Most people think relationships are either “good” or “bad.” But the Developmental Model of couples therapy describes something more nuanced: relationships move through predictable stages, each with its own challenges and its own gifts.
Here’s how those stages look:
1. Symbiosis (The Honeymoon Stage)
- High chemistry, low conflict.
- Everything feels exciting and new.
- Differences get minimized because bonding is the priority.
- You tend to idealize your partner, and that’s actually functional at this stage.
2. Differentiation
- Differences start to surface and feel threatening.
- Boundaries get tested.
- Conflict increases as each partner begins asserting who they actually are.
This is the stage where many couples panic and assume something has gone wrong.
In the Developmental Model, this stage isn’t a problem. It’s required. For many couples, it also activates old attachment patterns, ways of seeking closeness or protecting yourself that you learned long before this relationship. That is not a character flaw. It is neuroscience.
And it is exactly the kind of thing couples therapy helps you understand and work through.
3. Practicing
- Each partner begins exploring their individual identity more fully.
- Outside interests, friendships, and goals become more important.
- There may be more emotional distance as individuation happens.
This stage often gets misread as growing apart. But the way I was taught to see it, it’s actually a sign of healthy development.
4. Rapprochement (Coming Back to Each Other)
- Partners begin returning to each other with a stronger sense of self.
- Real intimacy becomes possible because both people are more fully themselves.
- Communication deepens. Repair becomes easier.
5. Synergy (Building Something Together)
- You function as a true team, each fully yourself and fully connected.
- The relationship is no longer driven by fantasy but by shared values and genuine love.
- Individual identities are strong, which makes the partnership stronger.
- Passion can return, this time more rooted and real.
Relationship stages therapy helps couples understand which stage they’re in and why the struggle they’re experiencing is often a sign of movement, not failure.
Dr. Ellyn Bader, co-founder of the Developmental Model, writes that couples relationships progress through five normal and predictable stages, and that getting stuck in one is one of the most common reasons couples seek therapy.
Falling Out of Love… or Falling Into Reality?
One of the biggest myths I see is that love should always feel like the beginning. That spark, that rush, that “can’t keep my hands off you” energy. Many of us call this “NRE” or “new relationship energy.”
As an LCSW and AASECT Certified Sex Therapist, I work with couples at every stage of this transition, and the fear of falling out of love is one of the most universal experiences I see.
But here’s the truth: Real love evolves.
In the early stage, attraction is driven by novelty. But a long-term connection is built through vulnerability, trust, and shared growth. It’s not always sexy, but it’s deep and enduring.
So if you’re wondering, “Am I falling out of love?” ask yourself this:
- Am I still curious about my partner?
- Do I feel emotionally safe with them?
- Can we talk through hard things?
- Do I still want to grow with this person?
If the answer is yes, then chances are, you’re not falling out; you’re just moving forward.
I worked with a couple recently who came in convinced their longtime marriage was over. They hadn’t argued about anything major. Their relationship felt flat.
What we discovered together was that they were deep in the Practicing stage, both focused on individual growth in ways that had pulled their attention away from each other. Once they understood that, the flatness made sense.
It wasn’t the end. It was a developmental moment asking for attention.
Doubt Is a Normal Part of Love
This one’s important, so I’m going to say it again: doubt doesn’t mean your relationship is broken.
Every couple questions their connection at some point. Every couple wonders, “Is this as good as it gets?” or “Why don’t I feel the way I used to?”
These thoughts don’t mean your relationship is over. They often mean you’re ready to stop living in the fantasy and start building something real.
Conflict Is Growth Trying to Happen
A lot of people assume conflict is a bad sign. But in relationship stages therapy, we look at conflict as an opportunity.
When the honeymoon phase ends, and tension starts to show up, it’s usually because your emotional needs are becoming clearer. You’re trying to be seen and understood. And your partner is too.
Healthy conflict helps you:
- Set better boundaries
- Express real needs
- Move out of people-pleasing
- Get to know each other beneath the surface
You can’t build true intimacy without going through the hard stuff.
How to Handle the Honeymoon Phase Ending
If you’re in that in-between stage no longer high on love, not yet stable; it can feel confusing. But you’re not stuck. You’re evolving.
Here’s how to move through it with grace:
1. Normalize the Shift
Tell yourself (and each other): “This is part of the process.” It doesn’t mean you’re broken. It means you’re growing.
2. Get Curious Instead of Critical
When things feel off, don’t rush to judge. Ask questions. Be curious about what’s changing inside you and inside the relationship.
3. Make Time for Connection
Just because the spark isn’t automatic doesn’t mean it’s gone. You may just need to be more intentional: schedule check-ins, prioritize intimacy, and keep showing up.
4. Stop Chasing the High
You’re not doing anything wrong just because the butterflies are quieter. That calm you’re feeling? That might be safety. And safety is sexy too, just in a different way.
You’re Not Alone, And You’re Not Failing
If you’re reading this because you’re afraid your love is fading, take a breath.
What you’re going through is normal. Painful, sometimes. But normal.
I work with couples all the time who feel like the spark is gone, only to discover that there’s something much deeper waiting underneath it. Passion can come back. Trust can grow. Love can evolve if you let it.
The honeymoon phase ending doesn’t mean your love is over. It means your love is maturing.

FAQs
Why do relationships end after the honeymoon phase?
Many relationships end after the honeymoon phase because couples panic when things start to feel different. They assume change means love is gone, when really it’s just shifting into a new stage. Without tools or support, some couples struggle to adjust to this change and call it quits too soon.
Am I falling out of love or is the honeymoon phase over?
If you’re feeling less excited or more irritated, it doesn’t always mean you’re falling out of love. It could mean the honeymoon phase is ending and you’re starting to see each other more clearly. This is a natural shift and often a sign of growth, not failure.
Why doesn’t the honeymoon phase last forever?
Because it’s based on newness, idealization, and brain chemistry that naturally settles over time. As the relationship deepens, those intense feelings calm down, making room for something more grounded and real. That’s not a loss; it’s a transition.
How to handle honeymoon phase ending?
Start by understanding it’s normal. Focus on communication, build new routines of intimacy, and stay curious about each other. Therapy can help if you’re stuck, especially in understanding your emotional needs and how to meet them together.
What is the hardest phase of a relationship?
For many couples, the Power Struggle phase is the hardest. This is where differences become obvious, conflicts increase, and both partners start to fight for space or control. But this stage can lead to a deep connection if you work through it rather than run from it.
