I feel like I'm close to escaping limerence... but she's just so pretty!

I thought about writing my life story, or about my coworker, but it feels pointless. Any justification of the situation doesn't absolve the fact that I'm a shitty person.

I (25M) have been feeling limerence for a coworker (29F), but quickly tried to back off as I am already in a LDR, plus I felt my interactions with her were affecting my relationship with the other colleagues.

When I initially started backing off, we were still on very friendly terms. She would often sit next to me at lunch and would mostly talk to me. But then, she started talking to other guys. It filled me with a mixture of jealousy and shame.

I said to myself, fuck this whole mess, I need to focus on myself and my girlfriend. I started going to the gym during lunch, thus avoiding her almost entirely. I could go a whole week only seeing her a few times. I also would say things to her that would make myself seem less attractive. I felt our distance increase. It was bittersweet but I felt it was for the best.

It wasn't without its issues. The few times a see her, if she was alone, we'd have a nice conversation and I would feel the limerence resurge. If I see her talking with somebody else, I would still feel jealously, albeit less so.

Now I'm at the point where it's obvious that I'm avoiding her, and she has started to avoid me as well. I also don't feel much jealousy anymore, maybe a bit of sadness that I couldn't just have a normal friendship with her. Regardless, I started feeling like I could see the end of the tunnel.

BUT SHE'S JUST SO PRETTY. My avoidance of her has mostly severed my emotional attachment for her. But by avoiding her so much, she has somehow become attractive. Just a passing glance of her makes me go crazy. Going to the gym at lunch has become a routine and I don't want to stop regardless. But I'm afraid that it won't fully remove my limerence, maybe ever.
