I think I love my friend

Gay (20) I'm at uni with a guy who ive been friends with for about a year. Since the start he has opened up about his sexuality to me and he's bi. But it's not until recently that he's said to me that he might be emotionally attracted to men as well as physically. We have some fun sometimes, just playing around on snapchat and I don't know what to do. I think I might want a relationship but not sure if he's emotionally attracted to me or if he just wants to fool around with no strings. Feel like if I ask we wouldn't be able to just be friends if he knew how I felt.
