@crazykitten20, it's nice to have someone on here get it.
It's so hard because MIL comes across as lovely and actually she is in many ways. I'm always going to be the unreasonable one in a lot of people's eyes. It's the intensity of the relationship she wants with DH and me too, it's overpowering. She is mostly a good grandma to the DDs, with the blip described in my previous post. DD2 can be very clingy and she's been like that with most adults apart from me and DH. DD1 loves her grandma.
It's about boundaries. She and DH's late FIL always allowed their lives to be dominated by their parents and she's always expected the same. The first issue to.come up was what I would call her. I refused to call her mum, I called her by her first name and have stuck with that. I remember her saying in my hearing that her MIL would have been devastated if she hadn't called her mum. But I just don't want to.
The reason it's gone on so long is that 8 months after DH and I got married, my FIL died in a car crash. Obviously MIL needed a lot of emotional support and for at least a year afterwards DH was calling her every day. But we were also having to support my DSIS, who was going through a marriage break up having been a victim of domestic violence. And we were also going through infertility, hence why we eventually adopted.
And now I'm dealing with traumatic memories of childhood abuse. So I did need my DH's support as well. (I think she forgot that he himself was grieving his dad as well at times, she relied on him so much.)
BIL and his DW had small children so BIL was better at maintaining their boundaries and still are.
Long post. It's not something that's easy to ahare but at least this is anonymous! Thank you for your supportive comments.
Hope you're in a better place now?
