Years ago, I lived through conscious bitching from my Mother in law and one day, I just exploded and told her what a useless excuse of a woman she was!
you hubby needs to handle it if you want it to stop!!!!!
Just say "Oh! Really!" each and every time she offends you. She'll give up after a while.
you clearly need more practice
Move farther away.
Shut up you *****.I am NOT listening to your toxic bullshit any longer.<br />
But maybe your husband cannot stand up to her either.
stay away from her
Are you by any chance an Indian? Indians usually have that kind of a culture of taking care of parents. I suggest, stand up for yourself when it gets too much.
try answering "yes dear" every time she says anything mean to you. and say it with a big grin....eventually she will realize that is the same as being told "f*** you" with a big grin.
Make her move away or you move away :)
