I can relate with a similar situation! SIGH. For me, it was my second time having sex and it was a tinder hookup. I went over to his place, we watched tv, had some drinks and joked around. I enjoyed his company and the sex. His replies were slow after and he didn’t seem keen to see me again. I felt like I would of been kept around as a backup booty call at best so I deleted him on insta. That was almost 2 months ago and I’m still thinking about him. But what I’m realising is that I’ve just made a fantasy of him in my mind, he might of ticked some boxes but I really don’t know him. Tbh I’m keen to meet some new guys and I hope he’ll be forgotten. I just can’t right now since we’re in lockdown in Aus so he’ll continue to play on my mind, ah the suffering! It sounds like you knew this guy a bit more though, since you were mutuals but maybe you’ve also just played it up in your mind like I have? There will be other guys we have a good time and good sex with right?!
