agony, I'm glad you spoke with an attorney. Do you live in the U.S.? Did you know that in all states you can get a "no fault divorce" and so you don't have to show grounds for divorce?
Here's a little reference that explains about No Fault vs. Fault divorces:

Anyway, if you really want a divorce, you can ask your lawyer about "no fault" divorce. I actually don't even know which kind I am getting, but there are grounds for divorce in my case, but we may be doing no fault. I don't know, the issue has never come up with my lawyer. I don't think in our case it matters. We are doing collaborative, but I am going to be the petitioner (the one who asks the court for a divorce).
I'm glad you and your H have resolved the car issue. I hope it will be the first of many agreements between you in this process.
