Why do you assume the person posting is a man?
In case the poster is female- I will add- Some men are super bad about going after custody of the kids, as vengeance. Men will try to hoard the money (even wifeanon's money) in an attempt to control the situation, and sometimes, they will lie about wifeanon, to take children as revenge for divorce.
Some men will become violent, so always protect yourself. Put kids first, and watch what you say due to he could be recording you, to make you look bad in court. .Start getting your evidence, NOW. Lock YOUR money down, so he don't take everything and leave you penniless. Some judges will give the kids to the man, if he makes more money than you. If he's violent, change the locks on the house.and get a protection order from a judge.
