I have two issues mt three yr old never says she loves her daddy. I know that he is mean and as soon as I can I'm moving away from him I want to understand what is his problem with her is it the fact that me and him don't get along and he's unemployed and un happy with himself and want to make everyone else miserable. Alao he ha sa daughter who comes and goes every weekend but when she's here he's mean to the kids that live with him especislly our son who spends most of his time with him. When his daughter comes around he doesn't want my son to talk (my son stutters) he spanks him for the dumbest things and he gives all his positive energy to her lets her do what ever she wants and holds conversation with her. He never shuts her up when she talks but when our son talk right behind her he tells him yo shut up my question is what could his problem be.my 8 yr old says his daddy and his sister (on his dads side makes him so mad that he wants kill himself. Should I get him proffessional help [I] believe his daddy is the reason that he stutter

Yes. Some counseling might be a good idea. Already being suicidal at 8 is o good at all. Who knows what their father's problem is. We can all guess, but no one can say for sure. Focus on your children. Get them into counseling and keep working on getting out of there.
