Please give your opinion or advice

Me and my husband are temporarily staying with his mom to help out when we moved to his home state.

My husband and mother in law get into an argument over the use of a chair. He wants it in the room we use and his mom wants him to use one from the basement. My husband got angry and threw the chair knocking a hole in the wall. He didn't mean to apparently.

I eventually went outside to sit outside and call family to give myself time to calm down because if all I did was think about what just happened I was going to get more upset over it.

He at least tried to patch it up after but refuses to appologise to his mom and doesn't see him being part of the issue as a reason to appologize. I can't make him do anything he really doesn't want to do of course.

I'm just mad and disappointed 😔.

Just wondering if anyone has any advice for dealing with something like this or any opinion. How would you have felt or handled it? And at what point is someone's behavior and choices too much to sustain a relationship? Where's that line you draw and say if you cross it we are done? I'm not to that point though just want to know.
