supervised visits

After the final hearing the judge awarded me custody of my boys with supervised visits. Problem? She wants to spend all her time trying to get me to remarry her. She yells scrams calls me names then begs crys and calls me more names threatens to take me back to court here in TX . This scares me as I have head alot of horror stories about unfit mothers getting custody just because they are the mother. She was taken in to the mental hospital by the Army and they tried to commit her when she went crazy at the hospital with screaming yelling and being totally out of control when they would not kick me out of my home and give her the children. I was told by a lawyer to relax on the visits but my kids are scared of her before the final hearing she was stalking us and threatening the life of my girlfriend. And NO she was not the reason for the Divorce. My ex had asked for a Divorce and kidnapped my kids , She was a good friend before that and after she was there for me when noone else was and I realized this was the type of woman I needed and wanted i my life . Any Ideas out there ? I cant give my boys to a woman who was going to lose them to Social Services while i was in Iraq for Neglect just because she doanted 2 eggs to have 2 children she tries to use as pawns to get money . I have had to teach my children social skills , to rad at 8 and 10 , to tie thier shoes they have difficulty even doing normal things that Kindergarten kids find natural. Please any thing you think I can do please help
