Changed username but I've posted about my decade (and counting) of MIL problems before. She stepped everything up a gear once DC arrived, with grand delusions about the main character role she'd be playing in bringing up our children - tried to send me away to a hotel 3 days after birth of first DC so she could stay at home with my baby (not joking), opened all my new baby gifts while I was asleep, hosted guests in my house while I was sobbing into a breastpump hidden away upstairs. I naively assumed it would pass and we would somehow be okay but it's only gotten worse over the years. Nothing is ever enough for her and although they live 5 hours away from us she thinks we should all be up there so she can 'show off her grandchidlren' to her friends etc. She complains endlessly about us, compares us negatively to friends' children etc, and she's been awful to our DC over the years too - calling my daughter 'special needs looking' in her glasses, insiting they were taken off for wedding photos etc, gaslighting the children and guilt tripping them awfully - 'poor granny never sees you, won't you put flowers in your hair and dance for granny to make her happy.' She once turned around and shouted at my then 3&4 year old DC who were uspet in the back of the car with her, whinging for 'mummy', 'shall I start crying for MY MUMMY and see how you like it!?'. They asked for years not to be left alone with her as she was horrible to them if they missed us at all.
I can't do it all justice at all, and I'm not perfect, obviously, but when I had my third DC something in me flipped and I couldn't face them anymore. She came and complained he slept too much (she woke my first two up and I wouldn't have it the third time around), and finally, when we booked a trip up to see them and booked our own accommodation not the nearby cottage she had apparently booked without asking us she had the hissy fit of the century and sent tens of messages at all hours saying she had no reason to live if we didn't do as she pleased etc. It was unhinged.
I am friendly when they come to visit, but beyond that I have stepped away as I genuinely can't cope with her anymore. More to the point, my marriage can't survive it, my DH has fallen out with her along the way but it all eventually gets swept back under the carpet. If he ever really pulls her up on something specific she literally screams and wails at him denying solid facts. It's not something I can cope with, but it's obviously more normal to him and he has again now asked me to 'get over it' and go and see them at easter as she has been messaging him demanding we all go rather than just my DH and two older DCs. I was looking forward to a bit of a break! She has accused me of 'cancelling' her (Daily Mail reader) and seems to think I should just fall into line and do what she wants as she is entitled to us all up there.
I have dug my heels in and won't go, my DH and I are back into the same old cycles of it and he is asking why I can't just 'get over it' and go and see everyone. When I try and explain (for the hundreth time) he gets shirty and says 'that was years ago' etc as if I'm being stubborn rather than standing up for myself after years of this nonsense. I don't want any drama, I really just want peace and I have totally hit my limit with what I can tolerate. I'm upset that he seems to be thinking of it almost like he is caught between two difficult women and I really don't think I have been (I put up with so much for so long).
This is now so long, and I don't even know what I'm asking. Does anyone have any experience of this sort of stuff? Do I sound like I'm being obstinate now to stick to my guns?
TLDR: DH wants me to forget MILs decade of awful behaviour and go back to spending holiday time with them for an easy life.
