Secretly playing out his "alternative" interests which I finally learned about after 15 years, I asked him to leave after attempts at family counseling. I have full custody of two young children and he has maybe one to two weekends a month. We have no "official" separation docs, but agreed in writing to each other on custody wishes and financial responsibilities. He now wants me to sell our house and is trying to say he can raise the children any way he wants when they are with him, which many times is against our previous mutual agreements on child-rearing. What rights do I have to about being forced to sell my children's home, letting him claim one child on his taxes and allowing the children to see their dad but making sure they are cared for properly?
