Husband refuses to compromise

Background:

My husband and I have separate cars, we’ve always had separate cars and have paid for them ourselves without help from the other. When my husband got his new car he didn’t allow me to drive it or get into it without him despite being able to drive my car as he please.

Now I’m the one with the new car but I allow him to drive as he pleases even though he doesn’t follow basic rules like no eating in my car and no moving furniture in it. He even lashed out at me for not wanting our children to have snacks in it. I’m the only one who cleans my car so I felt it was a fair rule.

I understand typically couples share vehicles but this is what’s worked for us.

Now:

Someone hit my car and it has been in the auto shop for a week, the other drivers insurance is paying for a rental as we wait. This weekend I’d planned to take our children to do a few activities, my husband knew about this as it’s been planned for a while now. Since getting the rental car he picked up a few extra shifts at work so that he can drive it. On Saturday he is working 2 shifts and I asked him if he could drive his own car to work for one of those shifts to which he said no.

In this situation, he would drive the car to work and we’d skip the first activity and then we’d take the car to do the second activity and he would drive his own car to his second shift. Me driving his car isn’t an option as we live in Arizona and his car doesn’t have Ari conditioning. I have asked him to get it repaired but he hasn’t because he likes driving my car and once his is fixed he won’t be able to use that as an excuse anymore.

His solution is for us to do an activity in the 2 hours between shifts, which gives us two hours to get to the movies, watch the movie and get back home which isn’t realistic.

This bothers me because we sit in the house every day because any time the kids aren’t in school he takes my car to work and we have no way of getting around town. I try to be understanding because he’s taking it to work but I don’t think it’s 100% fair when he has a car but refuses to get the necessary work done to get the air conditioning running.

He is seemingly not budging so the kids and I will have yet another weekend stuck inside. This has been the same for most off the summer as well because he takes my car every day.
