Deck oiler: no contact broken during emergency but nothing resolved. Feeling guilty for NC

Bit of an odd update. We’ve been no contact and very happy. I still feel a lot of guilt. I know we are where we are because of MIL, her actions and responses. However I feel bad for my husband. He basically has no family. I know we are his family but I have a massive loving extended family and it’s hard watching him go no contact with the two people he does have (mil and sil). My parents live overseas so I also dread the day they have grandparents day at school and I’ll have to explain it to my kids

Hubby has an illness. I haven’t revealed too much about it because I didn’t want to put too much identifying information in my posts. It causes attacks where he gets extreme vertigo and nausea. The attacks have an impact on his hearing. The goal is to prevent attacks so his hearing isn’t impacted. It’s not permanent hearing loss. For example he had an attack, it caused 41% in one ear and it went back to normal after a long period of no attacks. While we can make changes to prevent attacks, we can’t control everything and sometimes he will have one no matter how many lifestyle changes he makes

He was working 1.5 hours from home and had an attack. He had to call mil as she was the closest person. She took the opportunity to love bomb him. Ranting about how much she loves him and would do anything for him. They aren’t an emotional family so very weird behaviour. He can’t stand up without throwing up and she arrives to find him lying down in the back of his work truck. She drives him home as it’s not a hospital thing because it’s a chronic condition and comes inside our house. He’s vomiting in the sink and she’s rubbing his back and I feel like a 3rd wheel in my own home. I thanked her for picking him up and she said you are welcome before throwing me an annoyed look and leaving

Now she’s been contacting him crying saying she hasn’t seen the children since May. He said your approach is wrong. You could have said I disagree with what you are saying but I’m willing to try to make things work. She said I can’t do that

She won’t admit fault and wants things to go back to before we confronted her. She’s even asked for counselling with me. I’ve told her that’s not going to happen. How can you mistreat someone for years and then be surprised they don’t want to see you? SIL blocked me on FB which is neither here nor there but it made hubby draw a line in the sand. He’s said he’s committed to our family and he won’t go where people don’t welcome me or treat me poorly

So it looks like no contact is either going to stick or they’ll send flying monkeys when it’s hubby’s and nephews bday later in the year. I know she’s an awful person but I still feel so sad for hubby and kids. People still love people who aren’t good for them and it’s still a loss. I guess I just need to come to terms with it all
