What to do when you don't like his gf is a good question. My son was dating this girl for several years. All they did was fight, fight, fight and fight some more. Sometimes my son was at fault.. sometimes she was at fault... anyway, they did not "blend" well.. After 3or 4 years, they broke up...In the beginning, I liked her.. Later down the line I realized I was not fond of her.. but if she is who my son wanted, it is his life, not mine...

In the middle of things a few times I mentioned to both of them that their relationship was not a good one.. The more I said the more they stayed together.. Then I said to my son and his g/f/..... It is your life and who you live with. Is your choice.. I don't want to be involved anymore... And I let go......... guess it wasn't long after I said that they broke up... shrugs shoulders...

Am glad they broke up.... The both said very harsh, ugly words to each other. Lacked communication...and compromise........Son had no respect for his g/f and g/f had no respect for my son...

So I'd say... from what I have learned is to stay out of it...
