So my daughter fathers asked her when her graduation was & she told him smh... Im pissed becuz he thinks he's going when he not invited & if he shows up at her school I will call the police. He has not been in her life in almost 11 yrs I have full sole legal custody. He only wants to be there becuz he relocate 3hrs away from us. But Im thinking about moving soon for the sack of my younger 2 kids.
