To heck with every thing else. Don’t even bring the car home and send your daughter and wife to a therapist. This is gonna mess them up. Especially your daughter.
And vice versa, of course. Sounds pretty normal to me. I recently spoke to one of my college professors from 44 years ago and when I mention being married 43 years, he stated " that means you learned to live with each other, faults and all". Yep.And yes, I'm aware that is a screwed up situation for a marriage, but he who is married that hasn't had his wife go off and do something not smart...I'd like to meet you.
I daresay in my marriage it's been me buying the expensive items that we regretted... I mean, I have a dislike/hate relationship with her dog, but that dog's costs pale in comparison to what I've spent on houses & cars.
But yeah, sometimes you just have to roll with it...
