Lack of time and money is killing us

I hope you can help us. My husband was married for fifteen years and had three beautiful children. His ex wife cheated on him and kicked him out. Five years down the line, the debts from their marriage is going to kill us for the rest of our lives. She makes it hard for us to see them every month and we still have to pay 390 each month.

It’s killing us completely and our seven month old daughter is suffering and she only gets to see her brothers and sister once a month, which is hurting them too. Please can you at least advise if we can speak that amount? I wouldn’t mind if we could see them more often, but she constantly obstructs our time with them.
