Am I a bad person?

Sooo, there's this guy I know who recently got out of a two year relationship. I know both the girl and the boy and are friends with them both. The boy and I have always had a weird connection from the first time we met and there's undeniable chemistry there, but I always ignored it since he was taken (yet not happy in the relationship, but I knew better #girlcode #beingacompassionatehumanbeingcode). Anyway, this past little while he's began complimenting me more appearance wise and is way more sociable towards me and more physical than he has been in the past (but we've always been testing the boundary between friendship and something more). I thought he was just being cool old Ryland like he always is, but a friend mentioned to me that it seems like he is interested in me as more than friends because he's not really hiding his infatuation with me. I don't feel I was the cause for him and his ex girl's break up, but I can't help but feel guilty none the less that he may like me, but at the same time it boosts my confidence. I'm not totally sure how I feel about him quite yet since I put my feelings for him on the back burner while he was taken, but I feel guilty because what if I do like him? He's hot, guys, and has a great personality. Eh, I just don't know how to go about this.
