I don't know if I'm more mad then hurt for my 2 older daughters. my ex-husband has been telling them for 2 weeks he will be here on Saturday to get them per our custody order. he texts me last night telling me it's mother's day and he doesn't want to get them because of that. I told him we are sticking to our papers since we are back in court for another custody battle and they are looking forward to seeing him. he's getting all mad upset and mean because he now has to come and get them this weekend. I can't believe a father would get so upset about having to see his daughter
