Boy Problems

so there was this boy who i really liked & he said he really liked me too. so we hungout for a couple days then he came over for a holiday & met my family. i did something horrible & slept with him the first night i met him. at the time this seemed like a great idea. he was really sweet & cute. a couple days after that this girl who he said was like his best friend told him things i did with her boyfriend when they took a break for awhile. so the dude i was talking too texted me about it & said we're done. of course i was upset & didn't think something that happened 2 years ago would affect me today. after about two weeks we started talking again just as friends. i ended up going to his house a couple more times & we fucked every time. we did the same thing every time i went over, we smoked, went in his room fucked then he would kick me out. after this happened twice i told myself i was done with him. the last time i was over there i had my best friend who was also one of his best friends m(not the same one who caused all the problems) come pick me up. we have talked since then & he wants me to come over n fuck him again. i still have feelings for him & i don't understand why if he only uses me for sex. but today i posted something about him on my snapchat & he replied back & we had a conversation & i told him don't worry about it. so of course i thought he was just gonna let it go but we talked for longer than i thought we would have. but of course i couldn't take anything for granted because 10min after we stopped talking he texted me again asking for nudes. i told him i wasn't in the mood. all i wish for is a second chance or to totally just stop having feelings for him.
