3 Reasons Why You Crave Highs and Lows as a Fearful Avoidant (Relationship Addiction)

Craving intense highs and lows in love can make it incredibly difficult to step out of toxic relationships and allow healthy, stable love into your life. If you find yourself addicted to these emotional rollercoasters, you’re not alone. As someone with a fearful avoidant attachment style, this pattern can feel almost impossible to break. Let’s explore the three core reasons behind this craving for highs and lows, and why it can feel so addictive.

1. You’re Used to the Highs and Lows

For most people with a fearful avoidant attachment style, the dynamic of highs and lows started in childhood. This often looked like working and working for approval, attention, or love—then, sometimes, finally getting it. That moment of receiving love or approval can feel euphoric, as if everything is finally right in the world. It’s a powerful high, a rush that says, “See, I am good enough. I do deserve love.”

This is your brain’s reward system at work. But inevitably, after the high comes a low. You might feel worthless, useless, or just deeply down. The cycle repeats: highs, lows, highs, lows. You work hard, you get the reward, you try to hold onto it, but before you know it, you’re back in the low and wondering how you got there.

This pattern doesn’t just show up in relationships—it can appear in other areas of life too. Maybe with money: you work hard, save up, feel secure, and then suddenly lose it and have to start over. Or with health: you’re doing great at the gym, feeling proud, and then find yourself back on the couch, wondering what happened. The core issue is that you’re used to this dynamic. Stability and safety feel unfamiliar, even uncomfortable. Everything is intense, and that intensity is a hallmark of the fearful avoidant attachment style.

The hardest part is letting go of this pattern—not because it’s impossible, but because part of you actually wants it. The highs feel amazing, and even the lows can feel familiar and oddly comforting. It’s addictive behavior: chasing a high, falling into a low, and starting the chase all over again. The highs bring you that sense of being enough, but you’ve learned that love is something you have to earn, not something you simply receive. Allowing someone to love you for who you are, without working for it, feels deeply uncomfortable and even scary.

And there’s another layer: the lows can actually serve you by breaking connection. They allow you to hide, to retreat from others, and to avoid the vulnerability of real connection.

2. Your Body Is Addicted to the Hormones

Beyond just being used to the pattern, your body can become physically addicted to the hormones involved in these emotional highs and lows. Dopamine, the “reward” hormone, is released whenever you get that approval or love you’ve been working for. It feels wonderful—but it’s also a key player in addiction. If you have addictive tendencies, you may have a lower sensitivity to dopamine, meaning you need more and more of it to feel good. This isn’t a permanent wiring of your brain; it’s often learned from repeated exposure to these dynamics, and it can be healed.

What’s especially interesting for fearful avoidants is the role of oxytocin—the bonding hormone. Oxytocin is released during moments of connection, like hugging, intimacy, or even breastfeeding between mother and child. It’s the hormone that helps us bond and feel close to others.

But here’s the challenge: fearful avoidants often have a fear of connection. While anxiously attached people crave connection and never want to lose it, fearful avoidants want connection but are also deeply afraid of it, usually because of negative associations from childhood. This means that even the release of oxytocin can feel threatening or uncomfortable. Your system can develop a kind of resistance to oxytocin—not a true allergy, but a strong aversion.

As a result, you might unconsciously break connection just as oxytocin is being released, or avoid deep connection altogether. This means you don’t get enough oxytocin to balance out the dopamine highs, so you keep craving more dopamine, and the cycle continues.

3. The Cycle Serves a Purpose (Even If It Hurts)

It’s important to recognize that, as frustrating and painful as these highs and lows can be, they do serve a purpose. There is a benefit to having them, even if it’s not obvious at first. The highs give you a sense of worth and euphoria, and the lows allow you to retreat from connection when it feels too overwhelming or unsafe. Your body becomes addicted to the rush of dopamine, and because you have a hard time allowing oxytocin and real connection, the cycle keeps repeating.

This dynamic can make you more prone to addictive behaviors—not just in relationships, but in other areas of life as well. The interplay between dopamine and oxytocin, and your resistance to bonding, creates a powerful loop that’s hard to break.

Can You Heal This Pattern?

If you’re worried that you’re doomed to repeat this cycle forever, please know that’s not true. You can absolutely heal from this. It’s possible to reduce your craving for dopamine highs, to become more comfortable with oxytocin and connection, and to allow yourself to experience deep, stable love. Your body is capable of adjusting and coming back into balance. Healing may sound simple, but it is absolutely possible, and you deserve to experience the richness and stability of real love.

If you’re ready to allow that deep sense of love and connection into your life, know that support and resources are available to help you on your journey. You are not alone, and change is possible.
