Spent the last two days with MIL and am exhausted with the effort of biting my tongue constantly. DH is middle child with 6 sibs. FIL died years ago. One of DHs sisters lives at home with MIL.
MIL is selfish and manipulative - playing DH and his sibs off against each other in every way possible. She uses the daughter still at home to remain financially solvent / pay all the bills but belittles her to everyone else. She constantly plays her children off against each other for financial gain or seeking attention. She has clear favourites (those who married into money, dont work, and have the money and time to indulge her) and points out to us all what they do for her and how she "might as well not have had any other children" - without any acknowledgement that everyone else is working full time and struggling to survive and simply don't have the means or free time to pander to her.
She is a hideous house guest - with fussy demands regarding food eg. Only eats 6 specific items from specific shops. She disappears into the toilet for 45 mins at a time - not so much of a problem now but when we used to only have one loo we had to wee behind a bush in the garden if she beat us into the bathroom at waking up time. No amount of begging through the door would shift her.
I could go on and on but essentially spending time with her is painful- watching her demand priority meals, seating and consideration without any consideration of other peoples needs, while seeing her manipulate her family.
The AIBU is this: I am plain speaking and known for not putting up with nonsense from anyone. However, I have known my MIL for 21 years and have never called her up on her behaviour / demands - nor do any of her own family. I have always figured that it will just call an almighty row and given that she is such s practiced manipulator that it will just make trouble for my own family. So I keep quiet, leave the room if it is really excruciating and keep mine and DCs contact with her to a comfortable minimum. DH is welcome to see her whenever he likes as long as she doesnt screw money out of our family funds.
So is it better to be a wimp and exercise tactful discretion in the face of manipulative / demanding behaviour from in laws or AIBU?
