He also is supportive of the decisions that I make about their care (not whether they're with Thom or me, which he has never expressed an opinion about but their day to day care),
Who cares?
He always said that he knew better than me how to care for the children and because of the things he told me about myself, I believed him.
Apparently he was right, huh?
The only way in which he has really failed them is failing to provide as well financially for them as he could because he spends his money on things he shouldn't
You have a computer don't you? That is money that could have been used for the kids too. BTW, do you pay child support? NO? Why not? They are your kids too, why should you not have to take responsibility for them?
