My head realizes that could happen, but my heart won't fess up. I can't think which is worse- if it actually works out and he's secretly abusive and everything his ex girlfriend said was true or if I say nothing when there could have been something that worked out wonderfully.
And no, I won't use the other guy as a crutch, even I can recognize that. He's not the type of person who listens without expecting anything in return. If anything, it'd probably make me withdrawn from most people except my closest friends.
