Don't get me started.
My MIL, an unremorseful OW & WW herself
who states that "she didn't do anything wrong,
& she was entitled to be happy",
blamed WH's A on me, that I didn't keep the house like a magazine, that I didn't wear makeup enough.
Her first words to me on Dday
(I asked him to leave & he went to stay with her) were:
"Honey, what do you expect him to do, grovel?"
Here is what I think the right thing for her to say to her son in that moment should have been:
" How could you do that to the mother of your 4 children, who has sacrificed so much for you & our family over the past 23 years."
There were many more comments, during the time that WH & I were separated while he would not stop contact with OW, such as:
"Honey, if you don't take him back, there will be 20 women lined up at the door for him."
Needless to say, I have had almost nothing to do with her since Dday (except that we were both at a family funeral, etc.)
These are toxic people. Part of getting healthier is to remove toxic people from your life.
