Crush on a "straight?" guy

So I've been crushing on this guy for the majority of this year now. He has had multiple boyfriends, and he just broke up with a boyfriend of 7 months. I've been getting pretty close with him and he told that he's not actually gay, but he wishes he was gay. I'm just really confused on what to do? Do I keep going after him or do I just be friends with him? I absolutely adore this guy but I don't understand what he means by him wanting to be gay, but he actually isn't.
