Search Results: online dating service

I have a friend who lives about two hours away from me, we met at a drama tournament. When we met I asked him for his number and we texted a few times that week but not that much, we saw each other the next weekend at another tournament and hung out basically the entire time. At one point we were both done with what we needed to do but we still had a few hours until the tournament was over so we decided to walk around the school. He told me that the reason he didn't text me much was because he liked me romantically and he had just got out of a bad relationship and didn't want to get attached. I was his first kiss that day and we talked for a long time. The only reason we didn't start dating was because of distance and because we had both recently got out of bad relationships and decided it was for the best. We eventually stopped talking.
A little after this year started he texted me apologizing for losing contact and told me how I deserve to be happy. I texted him yesterday and told him I'm going to be in his town in two weeks and he invited me to go to a church service for teens that he said he really likes. He seems really excited about seeing me. I asked him if he was going to prom and he said he didn't know. My prom is in his town because I do online school, so if he did want to go he would be able to.
We both really liked each other a lot back then, and I still like him. This was last school year. I'd really like to go to prom with him but I don't know if I should ask him. I want to be casual about it too in case he doesn't still like me. Should I ask him to go to prom with me?
