Baby Mama Drama!

Viewer Question: Hello I am a 29 year old black women and I have been dating my 31 year old boyfriend fro about 2 years now. He has a 5year old son and I have no children. The issue I am having is with is Baby mom. I know that she is the mother of his childrenand I respect that to the fullest I even tried to have an adult conversation with her but she is very disrespectful and rude. I was raised in a two parent household both my parents are still toghether and have been for the last 40 years. they taught me that when I accept a man that has a child that its a package deal which I understand and have no issues with that. Me and my boyfriend live together and so on the weekends when the son comes over when spend time together I read books to him talk to him about school and bond with him. I have a Masters degree in counseling and rehabilation so I understand the importance in education so I try to be a positive influence on my boyfriend son. Me and my boyfriend often argues about his baby mom because every time she calls him about picking up/dropping off details she always seem to bring me up in the conversation and says things like I need to have my own baby and so what I have an education that don’t mean nothing and also says that I will never take the place of her. I really love my man he is such a great guy, very supportive, works hard, cooks very good and doesn’t try to take advantage of me because I am successful. I have been in other relationships where men are intimated by me and he is not. I have talked to my boyfriend about the issue and we cant seem to come to a fair conclusion on what to do and how to handle the situation. Help please!!!!!!
