HELP PLEASE

Hi! I'm a sophomore in Highschool and I've been talking to this guy for about two weeks(he is a senior) and then Saturday we went out for a bit and it ended up with us hooking up( make out, feel each other up, and dry hump), which I didn't plan at all. He told me he wasn't really looking for a relationship(got out of a serious one awhile ago) but the thing is I really really like him and I thought I could have no feeling attached type thing but I can't...any help? Oh and this is kinda the closest thing I've had to a relationship which is pretty pathetic, trust me I know. Thanks y'all xx
