Do I show my toxic af sister in law love or carry on ignoring her?

I've been with my partner for 4 years and we are due to be married next year. The rest of his family I love and are so kind and loving they are basically my family now but his little sister and her partner are the thing of nightmares.

The first time I noticed she was toxic was one new years. I was living with my partner family during this time and I had really bad covid. My partner was taking care of me upstairs in our room and she insisted but we come down stairs and play cards with her..

It was so boring and I was sick as a dog. I couldn't even keep my eyes open. My partner Matt could see I was struggling so bought me back up to bed. Before I know it she's pushed me and screaming and kicking off because we're not playing cards with her. She was around 26 years old at this time.

We didn't speak to her for a long time after that and fall outs continued. She never said sorry and in the end it was me who has to encourage my partner to make up with her after seeing how upset it made my mother in law.

They've had many falling out after this and I've always had to be the peace maker.

But this time I'd had enough. My partner ran a business with his sister and brother in law. He was the brains of the business and only took them on because they struggle with keeping jobs and money so he was actually looking out for them.

After 5 years of business my brother in law kinda had a cancer scare which turned out to be nothing and he started running the business down to the ground behind my partners back. When ever he'd confronted them about this they'd gas light him. Eventually we all needed to be earning more money as we now had are own houses to pay for. So we gave up on the business but my sister and brother in law decided they deserved all the money in the business they ruined and stole all f it saying they needed the money more because they don't have savings like we we do as if that's are fault we don't piss are money up the walls

I'm not even finished there. We continued to try and stay civil but my partner was so hurt by his own sister doing this to him. At the end of the day he loved her and would have done anything to help her even when she treated him like shit back. He was in a really bad place after that and I was the only one there for him.

Then his sister has a "mental breakdown " because she's realised how much of a terrible person she is and we are all ment to feel sorry for her. She never said sorry

Just asked if we all hated her. She kinda guilt trip me into forgiving her and so did my mother in law. My mother in law is always making excuses for her instead of holding her accountable because she's scared of losing her even though as soon as her money ran out she'd be back. Its like they put me and my partners feelings aside for her because they know we are good people and they take advantage of are kindness
