No, you're not, but sometimes you're an obstacle that needs to be passed.
Owl, Floo, talk, send out smoke signals, I don't care how you do it, just get some form of COMMUNICATION going, because it will give you a hell of lot more answers than I can give you.
Eddie, calm down, okay. I'm not trying to deter you from doing something you want or convince you to doing anything you don't. But think about this (and yes, I know that is silly considering what I'm about to suggest): This is feelings we're talking about, so maybe you shouldn't think? Maybe you should just go to her and see what happens? If you talk, you talk. If you fuck, you fuck and then you can try talking another time, and if she kicks you out, well, then you leave.
I care about you, I care about Susan, and I honestly hate seeing you both with your knickers in a twist like are now. Believe me, if I could, I would wave my wand and make you both aware of exactly what's going on, but I can't.
