I live in Iowa. My wife was unfaithful and I have filed for divorce. She had children from a previous marriage when we met and I have been their Dad for most of their lives. I have moved out and my wife said she doesn’t want me to see the children. I want to avoid legal problems but I also don’t want to lose my relationship with my kids. What is my situation and what can I do? Would it make any difference if the children’s biological father gave me his permission to see the children?
