When my husband and I first got together he use to talk to his ex girlfriend all the time cause she was with one of his friends. I despised that woman
Yikes, that's very disrespectful. I hope you told him how you feel about that.
I did, he said she did not mean anything to him and stopped going over to his friends house 
That's good, at least he learned from that. I hope you guys are going strong now!
