Will a guy really spend months talking to you just to get in your pants?

So I started texting with this boy in April during quarantine, we have a lot in common so we were talking everyday A LOT, deep talk, dumb talk, everything. So eventually he told me he was into me and wanted to meet blablabla. I told him that we’d have to wait until I finished my exams, alright, and also that I had never been on a date DATE before and it made me kind of nervous, so we talked about it and he understood saying he meant no pressure, no sexual intentions (haha). Finally last week we met and everything was cool, we went to the beach and spent the afternoon just chilling, talking etc just great. at some point we started making out and he asked me if I wanted to go to his apartment… you know. I’m usually super anxious about this stuff but for some reason I had felt super comfortable with him all the time so I didn’t think much about it and agreed so we had sex. oh I should mention I literally told him I was on my period and he didn’t care lol so I said fuck it then… and he did ask me whether I felt good or I wanted to stop you know he seemed caring and all. HERE’S THE THING. It was my first time and it was messy as fuck I guess anyone who has had sex (I’m a girl) knows what I mean. But overall things weren’t awkward or anything so yeah I said let the show go on. We spent some more time there afterwards and then he drove me back home. Since that he didn’t text me back or anything so I texted him four ??? days later to check on him and basically he told me he can’t be friends with women he got attracted to, that it’s better we don’t meet again because he sucks as a friend and will disappoint me, saying he doesn’t feel attracted to me anymore… I’m like well if you you want to meet again I can’t pressure you obviously but 1 saying he sucks as a friend and all that shit after all that time?? after telling me all his life problems and shit?.? and 2 if you don’t feel attracted to me anymore well then there’s nothing I can do about it but does that mean we should stop talking at all. Also I asked him if he just wanted to have sex why didn’t he tell me or at least not tell me that he had ‘no sexual intentions’ and he deadass said he likes to get to know girls he has sex with… boy… I just find everything so messed up like ??? btw we had talked about relationships before and we both had agreed that we weren’t looking for a relationship but this? wtf Any word of advise would be nice I’m just so confused ahaha and sorry for the long post x
