He led me on then rejected me?

So this guy started talking to me in class (were seniors), eventually got my number and has texted me almost every day for the last month, sometimes more than once a day. We've talked about everything and I really opened up to him. He went out of his way to switch lab groups to work with me in class. He complimented me, and not gonna lie we talked about sex and that kind of thing but I told him I wouldn't do it right now. He also like felt my butt once but that was it. So today after school he texted me, it was a normal conversation, and he even complimented me on my outfit and said he wanted to see what's underneath (obviously partially joking around though). Then I told him my sister told her friend we were dating and that if he heard that rumor that's where it came from. And I guess that got him thinking because then he went into it hard and pretty much broke my heart.

He said how he didn't want a relationship and sex wasn't his thing (even though he told me he did want a relationship and every time we talked about sex HE brought it up and I told him I wasn't really into it). He said that he had family issues to deal with and was scared of getting hurt, and I told him I understand but want him to trust me because I'm not gonna hurt him. He also said that my comment about wanting to go to prom with him caught him off guard (another guy asked me that i turned down). Idk how that's possible when we've talked about so much deeper things than prom. I just don't understand how within minutes he can go from complimenting me and completely leading me on to telling me he doesn't want a relationship.

ithink it's a bad time for a relationship anyway but I'm still hurt that he led me on and I fell for it. He said he wants to keep talking and thinks he wants to ask me to prom but just doesn't know. How do I handle this? I don't even know how to feel especially after turning the other guy down for him. What do I do?
