All that 'whores over bros' and 'bitches before bros' is a statement made by jealous friends who can't get no pussy themselves. Don't feel bad about it man lol, if he's a TRUE friend he will understand.

You didn't do wrong, you didn't run away with her and put the girl over him like that, it's just a fucking seat. Props to you for feeling bad about it, that's all that's needed. The acknowledgement that you MAY have done wrong. Top man.
