<human>: I've been the victim of the hit-it-and-quit it / the fuck zone a lot lately and it realllly sucks.

I'm not even talking like the one-night stand kind of hookups, where it's typical to hit-it-and-quit it. That's happened before and it's been no big deal.

But this is how it usually goes for me:
- Meet a guy
- He starts texting/snapping me all the time with him initiating probably like 4 or 5x a day
- We go out on a couple of dates and have a really good times
- I start to like him and have a feeling he feels the same way
- Texting/snapping still happens
- We hookup usually around the 3rd or 4th date
- He gets distant, the communication dwindles or if he does want to talk, it's only about sex 
- Everything stops, despite my attempts to get it back on track and I delete them

It's just SO heartbreaking to feel like you have a connection with someone, only to realize they only saw you as a conquest and all of the nice things they said and did were just to get you in bed. There are tons of girls out there who are willing to hook up but why manipulate the ones who clearly want something more? I've cried so many tears over these jerks but it just happens again and again.

Give me the gist of the text in a nutshell
<bot>: what goes through the minds of guys who go on dates with you, only to disappear after sex? Is all of this done on purpose or do they just lose interest and not know why? How can I avoid these people?
