Emotionally cheating bf/ another chance.. is it fair for me to tell him what to do with this girl?

well im a guy, and from all points of views....its best if he breaks all ties with this woman, its unhealthy for him as well as you for him to have constant contact with someone who he had feelings for and was actually willing to break up with you over. He has come to his senses thankfully for you. So ask him in the nicest possible way to consider how he would feel if the situation was reversed. What would he want you to do with another man??? You arent being unreasonable. Dont meet her if you are an emotional person, because you will picture this woman more often than not and eventually your relationship could break down. I'm not saying this is definately how it will pan out....but its a scenario you want to consider. Hope this helps.
