I really like him....does he like me back?

I met this guy on twitter and after a few DM's we found that we had a lot in common.We talked a bit after that and kept regular contact for the next few months. He got an Instagram account soon after and followed me. He would like my selfies....but only them we also had a few flirty chats in the comments of some of my pictures. I then got some questions on ask.fm and I knew it was him....he said I was hot and that he had a crush on me. Soon after he added me on Facebook and I think he likes me.....I want to ask him but I'm afraid it will ruin our friendship if he doesn't and I would hate that because I think I'm madly in love with him......HELP?!
