He signed and had notarized a legal agreement giving up all custody (physical and legal... I had all legal anyway). He is voluntarily choosing to not be a part of their lives.
He also signed a doc stating he will move out of the town we live in by the end of October and never live within 300 miles of us.
While I am happy to have a good bit of my fears removed I can not shake the feeling he is up to something. He still has to pay support or well, collect arrears since he hasn't paid anyway.
It just all seems too good to be true but I hope this starts a new, relaxed and happy time in my little family of three's life.
