2 years ago, My MIL disowned me 35f and my husband 35m for not baptising our kid, kicked us out of the house and told us we're not welcome in her house and went on a smear campaign against me, telling lies about me to my own parents and pitting his siblings against us. She told my husband that his father will die because he's not baptising our kid and blamed me for not knowing how to convince my husband to baptise our kid. She's made it clear to not call her grandma or mum because of this. She's incredibly toxic and manipulative, I suspect she's narcissistic. I felt sorry for her because FIL was diagnosed with cancer, but when my husband confronted her about her abhorrent verbal abuse towards me, mil said she is justified because she feels she's allowed to speak to daughter's in laws whichever way she wants. They refused to attend their granddaughter's birthdays parties and never reached out. So my husband wanted to go no contact and I was grateful as it improved my mental health greatly not having to deal with the MIL.
Anyway, this morning the MIL calls my husband to inform him that FIL is deteriorating and she apologised to him about her behaviour 2 years ago. I was not part of this conversation.
Do I have to just move on now? She apologised, but not to me directly and I haven't been given a chance to tell her that her behaviour is not tolerated. How do I bring it up without looking like a a-hole because her husband is on his deathbed? Do i have to have a relationship with her. I don't want to be difficult, but at the same time I cannot tolerate her verbal abuse and her spreading lies.
tl:dr 2 years ago mil aggressively disowned us for not baptising kid and then went on a smear campaign against me. She's now apologised to my husband. How do I navigate my relationship with her moving forward?
