Sure, I mean I would feel a little insecure but I still would. That is because I would trust you/ the girl I'm about or am already dating! If you can't trust your partner than it can never be true love, and trust is one of the biggest things in a relationship you know!!!
Depends. You see him like a brother, but the quesiton is what does he see you as. I have only dealt with girls who had kept in touch with their exes. Now THAT is a bad sign. I would have to be around both of you to make my judgement
I was hoping these guys would say yes. My best friends are guys and people that date me better trust me anyways and realize me and him are just friends and nothing more. They aren't going anywhere so they have to accept it.
