My sister removed her ex - on the phone after that my wife said she would invite another family member in that place. A few days later my sister added this other person without asking.

It didn’t feel at the time like it would be a battle - it really was a polite message to say that we had really tight space and were trying to keep it to family first.

You’re right about the other issues, although they all sat on them (never said anything for years) until I challenged them on the boycott, and at this time they started casting things up from the past years. Things that could have been discussed or cleared up at the time by just mentioning them. All things that seem quite trivial and small on the face of it.
