My ex husband and I have been working out to make everything easy for our daughter. I read books and articles such as this article Custody and Visitation after Divorce and it helped me a lot. But it seems my ex has not been very cooperative. Lately, when its his scheduled to see my daughter, he often cancels it. He said he has some urgent things to do. What other things could be more important than our daughter? What will I do? Should I tell my lawyer about this?
