How mean does this sound?

To tell someone they are useless from the inside and useless on the outside.

-Referring to a deadbeat ex, I usually don’t put up a fight or anything but today he pushed my buttons about our daughter. He is useless he doesn’t pay child support or work I have full and sole custody of her and legal custody. He tries to wear me down every second he gets and It’s not working. Like seriously he has a restraining order and we are only supposed to talk about our daughter and briefly make contact when he has visitation but he broke the rules. I want him to see her once a week not twice if I reported him I wonder what the judge would say...
