I don't know about "guy rules", but in "girl rules" dating your friend's EX is a big no-no. I say leave them alone and move on to someone else. Be a good friend to the girl. They will soon split up and maybe she will turn to you. Patience!

If your ex is dating a man and a girl at the same time and you have proof he is having a relationship with the other man then your ex is bisexual. Be sure he is simply not buddies with the other man.My ex is a girl and I have valid proof that she is dating them both. I just do not understand why. What is the point in being with two people at once. It does not make sense to me and it is a little gross to me.

Nothing. At 18 and 21 you both are adults.
