very proud but still can i slap him?

just kidding but like really. So i am proud of my ex that he has now decided that he wants his visits with his daughter to be uninterrupted. so glad he is now taking some interest in one of his children now he needs to step up for my son! has not called once to check up on him nor tried to see him in a week. my son deserves better. so does my sons sister... im getting irritated by him
