Which guy should I choose? Please help?

Ahh this is why I don't think people should stay too close to exes. If your ex is not willing to be in a relationship with you, it's not fair for him to keep you in limbo and prevent you from moving on with other relationships, and it's not fair to this other boy that you like for you to be juggling both guys. I think in healthy relationships you either have to be in or out. No one can tell you which one to choose, but you need to make a decision. You can talk to your ex about it, but if he doesn't want to be in a relationship with you, then the other guy will probably work out better.
