I am 47 yo female.  No married but living with 53 yo father of 3 for almost 5 years.  I have one daughter of my own who is grown and has her own family.  His oldest is 31 and has his own family. #2 is 18 and I get along with him great.  His youngest is the issue.  He is 16.  The first 4 years he was awful to me. Everything I said or did was "mean" and reported it all to his father  who didn't understand I was only trying to teach him to be respectful.  His father "disciplined" me.  He made hurtful comments about the food I made, my hair, how big I was.  Everything.
