It shouldnt matter how much it will cost to fix the van as the van is HER problem. She isnt footing the bill(s) for your vehicle therefore there would be no need for you to foot the bills for her car.
Its very easy to get your name removed from the title of a vehicle pending your bank loan is paid in full. Again, some simple research on your part could have made a huge difference.
You could have said "W, I understand the fix you are in with the van and the repairs but I feel its best for me to have my name removed from the title before you take any further action with repairs or the purchase of a new vehicle".
Its these snap decisions that get you in trouble. As I understand it there isnt any sort of "legal separation" in Texas but you can create a temporary agreement. I know this because I have a friend who lives in Texas who is about to go through a very messy divorce. Both my friend and her H had a temporary agreement drawn up so EVERYTHING was clearly spelled out with finances, vehicles, the home and so on. It protects you, your W and your kids until some legal formalities are initiated.
It doesnt really matter what you "feel like" paying for or not. Without some sort of temporary agreement that is signed and legally binding what you "feel like" doing wont mean squat.
