my ex-wife has physical custody of our 3 children, yet never has them with her. They have been staying with MY 74 year old grandmother for 2 months. I pay child support and have them when I am not working, but she will not turn custody over to me as she does not get along with my current wife. My Grandmother is caring for them because her living conditions and lifestyle are terrible. I feel like I have no rights...What do I do?
