Need help, im so confused?

I think I like this guy, a lot, idk he’s not my “type”, I have never liked a guy from church ever. I saw him there Sunday morning but we didn’t talk. I was disappointed that I didn’t get to say hello, but I left and went back to my dorm. I needed to do groceries and everything was closing because of the holiday. The store I normally go to is 25 mins away, my roomie told me of one that was in another town but it was only 15 mins away, so I went, and I was listening to music and every song reminded me of him, see i am not sure if I really like him or if it is a ping crush, anyway I was debating with myself but all I knew is that I wanted to see him. So I get there park and go into the store, and who do I bump my cart into, him. I think I became very red, he was surprised to see me but happy. So we talked and then I left happy to have seen him. The problem is his ex or current girlfriend. They started dating three years ago, but had a very public break up a year ago.
