Is it reasonable for women who have been divorced for more than three years to always ask their ex-husbands for money? I think we have been divorced for more than three years. When we divorced, we must have finished the division of property, and all the calculations have been made clear, so it is definitely unreasonable to ask my ex-husband for money. However, if two people have children, the child is awarded to the woman at the time of divorce, and the man fails to support the father and children in time after divorce, because there is no relationship between the man and his ex-wife, but it is still the obligation of the child's guardian and friend to support the children, so it is reasonable and should for the ex-wife to ask her ex-husband for money all the time.
