I just posted a question about my ex being an alcoholic.....?

WE have been divorced for 6 years now/ I tried to do this 2 years ago but the lawyer told me my chances were slim..I called CPS and they didnt give a crap..all they do is go there and ask him if he is an alcoholic..of course he says no and they say ok sorry to bother you. I forgot to mention that last year he had FELONY charges against him for child abuse allegations from his 9 year old step daughter, he took pre trial diversion. But his second wife has recently divorced him (He kicked her out to move in his best friends wife) and my son has been telling me more and more things..so the only witnesses i have are my son, hospital records, court records, the school counselor and his second ex wife. He already pays support..well he is ordered but he rarely pays it so i dont care about that. CPS wont do anything because they say my son is 12 and old enought to take care of himself and it isnt illegal to be drunk around your kids.
