I dont know what to do about this college guy?

I'm 16 and I'm staying at my dads house for part of the summer but its in a small town and I don't know anyone. I met this guy at eachothers work, we have always had little conversations and we would flirt a lot. He asked me out and since he's 20 ha I had to sneak out to hangout with him. There was nothing to do so we made a dare that if I lost this game I would have to kiss him so we did and I lost and we ended up making out. When we went back in his car we made out some more and he started rubbing my boobs ans my crouch then he started like kissing my nipple. Then I told him to take me home and we kissed goodnight. He also told me he sometimes smokes weed and partys he is also not a virgin. I'm a virgin I don't smoke and I don't drink he says that he is fine with it. But even though I know this relationship isn't going to happen because ill be gone in a couple weeks and he knows that but I felt like he just wants to have sex with me. And I know that that's what all guys want but everything went way to fast. And now he keeps texting me and I don't know if I should. I mean I liked making out with him and holding his hand but that was the first time I had madeout with anyone. Should I just stop talking to him or just hang out with him one more time to see how it goes?
