My MIL supports me but not to her face.
She will never tell my SIL the Truth of the matter.
My MIL just wants peace at any cost, even if the cost is my sanity or hers.
So I wrote her a short message and told her some things I knew about what she's been saying about me and husbando and her motives behind it and also that I didn't want any contact with her any more and she's banned from being a part of my family (husband and child's_) life.
I choked for a while to be honest. I don't want to stress my mother in law out any more, but the woman is tearing her apart. She is tearing ME apart.
Another story. On my kid's birthday (5 days ago now) she came over by surprise, and just waltzed into my room, walked in the door and I didn't have any pants on to say hi to my kid. When I was busy trying to get us both ready for guests we weren't expecting. Like... WTFS.
It was also the day we got the news my MIL's sister has cancer in her esophagus.
So later she proceeded to drink several glasses of wine and bitched to my MIL when she showed up 10 mins later about how horrible her life is -- for two hours. My MIL was just torn the fuck up, trying to hide it all and not break down at her grandson's party.
But she did break down eventually and my SIL's reaction was a cool "Oh I heard about that is she ok?" like it was the most casual thing in the world. MIL was very upset about how callous she was.
But I'm finished, I have gotten a lot off of my chest, and from now on that's it.
My MIL will have to respect my decision for the health of my family and sanity.
