Teenage relationship drama

Right so basically at a party last weekend I got with a friend and we did some stuff, he recently broke up with his ex who he dated for 12 months, then on Monday we kissed. I don’t think it really means much to either of us but I have caught some minor feelings, then tonight I found out he got with another girl and I’m going to a party which he will be at tomorrow and my friends have been telling me that he is going to hit on me and I don’t know if I should go through with it or not. I think we are just both lonely in different ways, I just haven’t had a good experience with relationships and he i believe is trying to distract himself from how sad he is about his last relationship ending. Either way I don’t know if I should go through with it if he tries to get with me tomorrow, I want to but I have a feeling that it’s a bad idea.
