Being used.

Tori
Recently, I can't find any guy that would actually be in a relationship. the last guy I had a thing with told me he liked me then after a while said he loved me and he had gone on dates and hung out but he always asked for nudes and I'd say no and he'd get upset and would be his normal self and seem down. then he asked for sex and I said no for the fact I'm not ready for that with anyone. and when I said that he instantly turned cold, he said he never remembered saying he liked me or anything to that extent. and my ex also did something similar when I said no to sex on Valentine's Day he didn't break up with me but he cheated on me. before he did that he would always say how he hated that we didn't make out like we used to and he'd start a fight with me when ever I said I didn't wanna send nudes to him because "I didn't trust him." I tried using apps to find someone around me and I stated in my bios that I won't haves sex and won't send nudes but because I'm "pretty" every guy I talk to thinks I'll send to them...
This is more of a rant than anything but I just don't know what to do no more
