are you responsible for mortage if you leave a marriage

This will be based solely on your situation and I'd advise you to take the advice of your lawyer for who will pay what. I hope this helps...

situation will give the proper answer for this query

If she is walking away from the payments, then I am sure you can arrange for her to be removed from the deed and any claim against the property. If you cannot make the payments on your own, then (with the help of your attorney) you may be able to sell the property and keep the proceeds.

you need to first get quitclaim from you spouse and refinance the loan in you name or if the loan has both of your names, then both of you are responsible.

eric, you are the lone wolf here. i see no need to add to your post.
