I haven't spoken to step MIL in 7 years due to her behaviour towards my DH, BIL and I (telling us we weren't welcome, telling me I would struggle to look after a child properly) in the past and her utter lack of remorse in the face of some truly outrageous behaviour and comments. FIL is finally starting to understand as he has found out about a number of lies she has been telling/ tells if things don't go her way with people and she has fallen out with both of her siblings and her mother due to 'slights' they have made against her.
We spend every Christmas at my parents as she doesn't want me at her house and whilst I would be perfectly civil and nice for my DCs sake, she will not do the same. The DCs are still little and people come to us, or we see them a few days after Christmas to give presents. This year, both DCs had a terrible virus which made them really poorly up to Christmas Eve, so DH texted his dad and step MIL to ask if they could pop over to us in the morning, and as MIL didn't like me, I would go to my parents.
Her response was that she was never going to get over how she has been treated in the past (mainly she feels she was ignored at our wedding, despite there being over 100 guests, some of whom had travelled hundreds of miles to see us and she refused to move from her seat or talk to anyone except FIL) and she thought DH should bring the DCs over for Christmas lunch every other year so it's fairer.
As I've said to FIL who was mortified at her behaviour, this isn't going to happen until she can get over it. DH and I have made it clear we are willing to just get on with life and let bygones be bygones as we've all had plenty of time to mature and mellow out and reflect/apologise for our behaviour or handling of the situation. I readily admit I didn't handle it well by completely withdrawing and being angry.
I was thinking of writing a letter to step MIL to apologise for my handling of things in be past and to say that I am happy to just get on with life so that wE can all enjoy the children, but is this the right thing to do? I worry I would be resentful at all the running and apology making and compromising, when MIL has already said she will never get over it and is still exhibiting the same behaviours she was when I last spoke to her.
Wise MNetters, what do you think? Sorry it's long!
