My ex-husband is proving to be a very untrustworthy and hurtful person to me, yet he is quite a good father to our 3 children. He also has another child from a previous relationship and their agreement is very relaxed between them but is legally 54/46 and he has always paid her child support. He has been and is determined that he wants 50/50 custody of children, which was fine but then I was told that if that happens, he never has to pay any child support. Is this true? He lost his mining job months ago and has since sent us into bankruptcy (haven't filed yet) and he's moved on and doesn't seem to care much. I made a lot of sacrifices with my own employment to enable him to work away from home, as he was doing it for his family. He has been a very controlling person and I'm positive that he will be returning to high paying jobs again soon and would love to know and see that I'm still struggling financially. He also gets his parents to look after the kids quite a bit, as 3 kids aren't easy to look after when it is something you are not used to doing.
