I told my ex to choose between his gf or his children...*UPDATE*
Sorry, maybe that sounds crazy, but he can choose. Either keep the psycho in his life and not see his kids anymore, or get rid of her and have his EOW.
I got tired of my kids coming home and telling me that she attacked their daddy with a pizza cutter, knife, hit him, kicked him, threatened to kill herself - all in front of my children!!!
If he wants to be abused and risk his life, fine, but my kids are not going to be in the middle of it.
I have explained my concerns to my ex, and he agrees with me. He will have the situation handled, whether that means kicking her out or putting her in jail or whatever before his next visitation. I asked him what he would do if the kids came to his house saying that my DF was attacking me that way, and he said he'd take the kids away from me and beat the hell out of my DF. And then he kinda saw my point. He is very distressed, he loves his gf, doesn't know how to do this, but he said that his kids are more important than her. He also said that he understands me keeping the kids away from the situation and will not take me to court for it if I keep them away until he can get her out of his life.
