I'd seriously love a best friend. Female, male, I really don't mind--whichever. Someone he's known since childhood. If you want to do the 'you're my best friend, but I'm in love with you' line, that's fine, but he's not going to be able to recognize it because he's eventually going to end up with his exwife.
I need siblings. Enemies. Anything. Not picky about the PB either!
