MIL has a terminal illness and it's looking like she won't be with us for much longer. Understandably DH is beside himself, he is very close to his mum and an only child.
I've never got on with my MIL as I feel like she's always given unsolicited advice, tried to get over involved in my parenting and in our relationship with DH (examples: got very offended that I didn't want to have a C section as she advised, said things like "mummy isn't being very nice" to my DS when I was attempting to put him down for a nap that he was resisting, given cake to DD "because it's what grannies do" when I specifically asked her not to). Because of that I limited the time I spent around her, although I never stopped DH spending time with her and encouraged him to visit solo, but DCs are very clingy to me so never went without me to see MIL.
Now that she's ill my husband keeps getting VERY angry at me that I didn't just tolerate her treatment of me, always saying "she didn't mean it like that", "she just wanted to be a hands on granny", annoyed at me that DC are much closer to my parents than MIL because we saw them more often, blames me for 'time wasted' that she could have spent more time with our DC. In my view I have never been rude to her or restricted her contact with DH or DC, just protected myself from stress and comments that I didn't like.
Unsure how to deal with this. Is he BU? Is this a natural reaction? How should I be responding? I don't feel like my mental health was or is worth sacrificing just because one day she would die earlier than me, but equally I see why he's upset.
