My ex-wife isn't a good mother. She has primary custody of my daughter but my daughter hates being with her. Shes about to be 5 but she has never liked leaving me and going to her moms because her mom doesnt really interact with her. She goes out on the weekends and leaves my daughter with her grandparents. Now, she is pregnant with another mans child but the man disappeared. She will now have 2 children working a full time job and no significant other to help her. She can't take care of my daughter properly. Anytime something happens to my child her mom calls me to see what she should do. Can any of that help me get primary custody?
