There is a recurring theme to your posts. You text... she does not respond... you get angry.
In DR, I was just reading about the tunnels and the cheese. You have set up camp in front of a cheese free tunnel. What you are doing, IMO, is the classic definition of insanity. That is doing the same thing over and over and expecting different results.
As far as the car payments go, I would just make sure that they get paid. It is obviously a source of concern on your part. You may not like having to make the payments but you are just as responsible, in the eyes of the lender, for those payments as much as she is. Do what is fiscally right. Personally, I think you are using the late payments as an excuse to text her. She just lies about it. This in turn makes you angry. Why are you setting yourself up for this?
When I went through my D with my first W, I gave all the creditors calling me about my WAW's debts her new address and phone number. Sure, WAW was not too happy about it but I didn't need the added stress dealing with debts that weren't mine. They were her debts and her concern, not mine. I refused to take ownership of her responsibilities.
When your W beefs about your relationship with her family, I might respond with, "I am truly sorry you feel that way" and leave it at that.
