I have a similar situation. I have not seen my dil and son and two grands 8 and 4, for 4 years. No response at all to calls, letters, gifts, so stopped sending gifts and cards. Text son once in a while asking for communication and reason for silence to no avail. Dil was raised in church, but denounced and is anti Christ now. She calls her mother stupid, says she only uses her dad to get presents, manipulated my ex into buying them a $35k car, got a house out of him. They lived with me for a while before children. She cursed me, yelled at me while drunk, called me a fucking bitch, used the F word liberally when I had guests over. Son tried to leave her, she threatened that he would never see his kids again. Brother has talked to him, he says it's my Dils problem. Dil says he has the problem and I am stuck hanging. She is very angry and controlling. He enables her. So now what?
