Sac-
I’m sorry, but just because you may have feelings for someone it does not mean that a friend should not go out with that guy. I’m really sorry that it didn’t work out for you, but we believe that everything happens for a reason, and if you did not marry him he was obviously not meant for you. Now that should give free reign to anyone else to try and see if he is their bashert. If not, then no hard feelings on any end, and if they do end up getting married that is just further proof that he was meant for her and not for you.
You dont own the dating rights to a person just because you may have dated them in the past. If we were talking about second marriages and someone’s ex husband, I think we would all agree that is a different situation?
