My MIL doesn't attract problems. She creates them.
Usually to put herself at the centre of attention if she feels knocked off her matriarch perch - or as a means of manipulating others when things don't go exactly her way.
I have known her 7 years and have literally lost count of the number of petty rows, huge arguments, episodes of not speaking she's had with friends and close family members including myself.
Aside from her, I'd be hard pressed to name more than 3 people I've ever 'fallen out' with, and certainly none since I left high school. I come from a family where we behaved in exactly the opposite way- drama was avoided. Problems solved rather than exploded into catastrophes. So I find it particularly hard to tolerate.
Then there's the lawsuits, cutting off her sister (for a very insignificant reason) and contributing significantly to the break-up of two marriages.
People like this are extremely exhausting and don't realise that it drives people away. I tried very hard to like her, forge a good relationship and focus on her positives.
Tbh, I'd rather just keep contact to a minimum now and I only make a minimum effort with her for the sake of my dc and dh.
It is truly a shame, as she does have some fantastic qualities, but honestly it's just not worth it.
