What do I do? Does he want a relationship with me?

So this guy started talking to me. My 'friend' and him had a small thing. But she fell for him . And he didn't. He told me he liked her alittle bit but he got bored of her because he just didn't have feelings for her. He told me he wants to be with me. And that I'm so beautiful. I told him I just wanted to be friends since him and her are very complicated.. but he said he hates her and he's making her life miserable.whje she found out we talking, she got so mad. I told her everything that he told me saying how he wanted to be with me and that I'm perfect and that I'd never like him. But he likes me.  She got pissed. She told me if I'm her friend I would unadd him because I'm causing more fire to everything. Because there 'complicated' I did. But then I realized I wanted to talk to him. I unadded him and he told me he can't be mad at me. He admitted to her that he told me all that stuff. He told me he doesn't like her. He likes me. And she can't stop us from talking. She didn't know I unadded him. So couple days later she says unblock him. He needs and wants you. Then she posted on social media that she's fespressed and wants to kill herself and she told me she's been crying for hours. Me and him talked on phone for 3 hours talking about everything. He asked If im a virgin I said yes . He said he wouldn't know how to keep his dick in his pants. I said your gonna have to, because I'm not planning on doing that anytime soon. He said ok , I understand that. If ur not ready, that's ok. I like you for u. I said thanks. He said he wants to protect me and everything. We talked in school and the girl saw us every day walking together. She's mad and telling everyone. Today we kissed in the hall. My first kiss. 4 seconds. He told me he's been wanting to do that but he's so nervous. What do I do? She's posting things like karmas a bitch and then she posted something like 'funny how u said ur gonna sleep but ur score is going up.' Meaning towards him that he's using snapchat and talking but ignore her. He told me he leaves her on open and that he moved on from her. She's not moving on st all. She's obsessed. In love. Crazy person. What do I do? Is he just wanting me for sex? He kept telling me he wants to be with me and that I'm his. We hug and he's so shy and nervous in person.
