Ok so my gf and I have been dating roughly 9 months. We are already talking about marriage and having kids. So we both know that this is a serious relationship and not just a fling.
 She has been separated from her ex husband for about a year. The divorce finally got settled about 2 months ago. 
They do have a beautiful 3 year old daughter, I understand that he will always be a part of our lives.
But.... I feel like if the conversation isn't about their daughter then there's no need for them to have a conversation. I understand that he is the father to her daughter but besides that he is nothing to my gf. So why does she have to tell him where she going or who she with. I've voices my opinion to her on multiple occasions but she gets mad at me saying that I'm just being jealous. She has also told me that the reason that he asks her about where she is at and with who is because he is trying to show her that he still cares for her and hopefully get back together... So am I in the wrong for asking my gf to stop having daily conversation with her ex that have nothing to do about their daughter?
