Anyone else get into a relationship during/after limerence and it changes your perspective?

I’ve had limerence on and off my entire life, but not a ton of actual relationship experience. This is the first time I’ve entered a relationship while still recovering from a limerence period.

It’s so crazy, while I was in limerence/heavy flirting with LO, I couldn’t understand why they wouldn’t just leave their partner. It seemed so simple to me. Now I’m in a relationship, and I see how much more complicated it is. It’s nuanced - they could be interested in you, but not want to give up an entire life with someone else. It’s not black or white.

But the other side of the coin is that I’m also kind of lowkey disgusted with how we both acted while they were partnered up. I would consider it micro-cheating if my partner did that, and I can’t believe I thought it was okay to kind of be “the other woman”. I would be devastated to find my partner maintained such a thing with someone else.

My feelings are really confusing right now. The limerence often felt so light and fun, but now it feels so messy and heavy. I’ve been focusing on my new partner but this keeps gnawing at me.

Anyone else enter a healthy relationship during/after limerence? Or have any advice?
