Don’t just assume your daughter is wrong until you find out the facts. Don’t just assume everything is her fault, you don’t know what caused this, and u don’t know how he treated her, and it sounds like you don’t want to know, You don’t even know what happened. Your daughter may have come to u as a cry for help, but you automatically assume it’s her fault. My dad did the same thing to me when he found out I was leaving my ex of almost 25 years of marriage, and my mother probably would have done the same thing maybe, if she had been alive then. the point is, that he automatically assumed it was my fault, I won’t give the details, but he was a judgmental racist and a pedophile, I can say that now cuz he is dead, and I have come to terms with the life I lived with my Dad and then my ex. Don’t be so quick to judge them until u have the facts, I would say more, but its already too late to make this long story short, all I am SURE OF IS THAT IF MY NOW HUSBAND HAS HELPED THRU A LOT, and rescued me from a life I couldn’t live anymore, he saved me from a life of hell on earth, and I am happier today than I ever was.
