Ancaire, They are bullies. I can't believe I'm reading this. I feel like you are dealing with junior high school kids, who's brains are still developing. Your attitude is awesome and you have maintained your sense of humor. You will come out on top Just give it time. Sorry you have to deal with all this though.
Pho, my mother had to deal with a passive aggressive MIL. Not as bad as yours, but pretty bad. (I heard nurses had to kick her out of the hospital when I was born) My mom basically did not encourage us to have a relationship with her and often complained and made fun of her to us (I know, not the moral way to go and very spiteful on behalf of my mom but I could see why she did it). We ended up never taking her seriously and just laughing and rolling our eyes when it came to her. It was almost like an us vs them situation and my dad just kept out of it or probably did know. Me and siblings would end up using grandma to play practical jokes on each other. We dont go out of our way to see her now but my poor dad trecks Across the belt 3 x a week to visit. MILs only have power when you allow them to have it.
