Mine was a sad ending I am afraid my Ex mother-in-law has narc traits - she was really unkind and cruel to me. We moved home to live at the bottom of her garden - there was no escape and my ex could not say no to her - It felt like there were three in the marriage. Eventually I had to leave I just couldn't live in that enviroment - it was making me ill! I still love my ex but as long as he has his mother and is tied to her apron strings - it would never have worked. I hope the outcome is better for you - don't let it get this bad!
