He just felt sorry for me

I was talking to this guy I hung out with and hooked up with before about a little over a year and a half ago. Anyways we were at an event and started talking and everything seemed cool. I sent him a message on messenger saying it was nice to catch up with him and we messaged each other and a couple days later I gave him my number and from there we texted pretty much almost everyday for about a little over a month. I started developing feelings for him, more than a friend. We then went to go watch a movie and everything seemed cool, we had fun and we ended up kissing then making out in the movie theatre. he was touching me and getting me really horny. After the movie we were walking around the shopping center and he was grabbing/squeezing my ass being all playful and flirty with me. We then ended up hooking up, no protection but he pulled out. He was acting pretty different and weird after, he asked me if I felt anything inside me, he said he almost ejaculated in me. After that he asked me if I was on the pill and I said no. then he asked me if I ever felt full like pregnant after sex or if i ever felt sick. i then said no then he asked me what would i do if he would've ejaculated in me. i found this weird but disregarded everything at the moment. We then go on our seperate ways and continued texting after that for the next 2 weeks or so. By the way when I got home i checked my calandar for some reason and noticed that it was the highest fertile days for me.okay comtinuing now, He seemed distant lately then recently a mutual friend of ours showed me screenshots of conversation between the guy I was talking to and him. He said that the only reason why he was talking to me was because he felt sorry for me because it seems like I have no friends and I was the one who initiated conversations and was bugging him to hang out so he felt sorry for me and went out with me but it wasnt a real date at all. He denied hooking up with me but the fact that he doesn't want to be friends with me, doesn't like me, thinks I'm drama and feels sorry for me??? what kind of guy pretends to be someones friend because they feel sorry
