I've become semi-attached ? When I first hooked up with him I was thinking in my head that this was a one time thing (ya know tinder). But then he didn't ghost me and contacted me a few days after the first time we hooked up. Ive always told myself sex doesn't mean I'm forever connected to someone. But the next time we met up and hung out, had sex and all and I started to feel some things. The third time we hung out almost a month later and I had the best time. But he hasn't talked to me in almost a week. If you want the timeline we started this thing Dec. 28 all the way until now (feb 23) so not that long. And I'm hating myself rn because I should've never let it go further. I didn't want it to come true, where after you have sex you catch feelings!! ahh, has anyone had a positive experience come out of catching feelings for a hookup? What was suppose to be a meaningless thing has my head fucked up and I can't stop thinking about it, maybe I can't have sex without a connection..
