Any moms that don't have contact with their kids, because of their own doing, I would like your input?

I have contact with my kid(s), but your story reminded me of my father. And if you dont mind I would like to answer, if they are strung out on drugs or alcohol then it doesnt matter they will just think you are being hateful. Either way, you guys are going to be the bad guys to the girls mother. But you have to do what is best for the child, and if that is keeping that women away then that is what needs to be done. Either way the mother is going to have a lot to answer for one day, on why she wasnt there and what not. So either way she has it coming to her. Or she could just be like my father and never think he ever did anything wrong and was the best parent in the world even though he is a drug head and an alcoholic. Good luck
