I’m studying abroad right now and my long-time friend 21M who i’ll call Jeff is studying at the same university as me. I dated my Ex for 3 years in highschool and we have been friends or friends w/ benefits ever since. However, a few months ago she started dating someone, so when she decided she wanted to visit me and Jeff (who she has also been long-time friends with) we were in purely platonic mode which I was completely happy with. Everything was going smoothly first few days we were seeing the sights, going out to bars, having lots of fun etc. But one night when we were out at a bar she started to subtly put the moves on me. I understand how it happened, it’s almost automatic with us having been in and out of an intimate relationship for so long, but I was legitimately surprised and did not expect her to make any kind of move while she was in a relationship. This is where I fucked up because of course I instantly folded and we ended up in bed together. We didn’t have sex though because that woulda been ‘real cheating.’ in hindsight, the emotional cheating we did was probably worse. I also want to be clear: I in no way intended for this to happen. I was not planning to homewreck their relationship and I expected her to remain faithful to her boyfriend. I kinda don’t know where to go from here. And I don’t know how to feel about her or myself. I’ve always thought of myself as someone with good values and I know what I should’ve done is refused her advances. Shes always done kind of crazy things and has a shit ton of childhood trauma but cheating is new to me. She was complaining about her boyfriend a lot the whole time so maybe this was her way of putting the nail in the coffin. Still fucked up on both of our parts though. AITAH? And what am I supposed to do now?
