I'm thinking of getting angry at my husband's ex over child support.
Have you talked to your husband about this matter?
I have done enough talking on the subject.
Your husband must deal with the financial matters with his ex. Jumping on his ex about the child support situation is interference. Let your husband work things out with his ex alone.
She was never around and all she sent was 25 bucks a month.
I can understand why you feel frustrated but this is for your husband to handle. The child support issue is a matter for the parents of the child.
