Hello!  
I’m a little embarrassed to write all of this, but I feel like maybe you guys could help me understand what happened.  
I’ve been in a long-term relationship for almost 8 years. I’m genuinely very happy with my partner and I don’t want anyone else. However, I’ve been feeling really guilty lately because I had a pretty intense crush at the end of 2025/beginning of 2026.  
In December, I started seeing a new physical therapist, and his practice is right next to our house. We basically share the same driveway.  
I had three appointments with him in December, and during those appointments we didn’t talk about anything personal at all. We only talked about the reason I was there and the treatment itself. There were also absolutely no signs from him that he was interested in me in any way.  
Then came the Christmas break, and I had one final appointment with him in January.  
Here comes the first thing I feel really embarrassed about: after my third appointment, the one right before Christmas, I was genuinely upset that I wouldn’t see him for such a long time. I was actually looking forward to my next appointment so much, and I felt really sad for the first couple of days of the Christmas break.  
I honestly couldn’t explain why. Like I said, we never even had personal conversations, and I barely knew anything about him. But for those two days, it genuinely felt almost like heartbreak. Like… what the hell? 😅  
Then January came, and after my last appointment I started deliberately creating these “random” encounters because I knew roughly when he finished work. I was basically obsessed with running into him, just so I could say hi or bye.  
Looking back, I find that behavior really creepy and almost stalker-ish, and it honestly scares me a little that I was acting that way over someone I barely even knew.  
At the beginning of February, I went on vacation with my boyfriend for a week, and afterwards it was basically like a switch had been flipped. The obsession with trying to run into my physical therapist was just… gone.  
I was honestly relieved that it stopped after about a month, because the whole thing was really intense and completely unlike anything I had ever experienced before.  
But now, half a year later, I still feel incredibly guilty about it. I keep feeling like I somehow cheated on my boyfriend, even though objectively, nothing actually happened.  
I never messaged him, never added him on Instagram, never tried to contact him outside of my appointments or anything like that. It was all in my head, apart from deliberately trying to “run into” him.  
Still, I feel like I put my relationship at risk simply by having such intense thoughts and feelings about someone who was basically a stranger to me.  
I’ve wondered whether it might have something to do with the fact that he was my physical therapist and was basically taking care of me and giving me his full attention during those appointments. Maybe being in a situation where someone is physically close, attentive and focused entirely on helping you can create some kind of emotional attachment?  
What also keeps bothering me are thoughts like: What if he had felt the same way? Would I have acted on it?  
And that question honestly scares me, because I don’t know the answer. I was also more easily annoyed with my boyfriend around that time, and I feel really bad about that in hindsight.  
This guilt has been eating me up, even though nothing actually happened.  
I started Googling all of this and came across the term limerence, so I thought I’d ask here and see if anyone has experienced something similar or has any insight into what might have been going on.

Thanks for listening :)
