There's a side benefit to that technique: if it doesn't save the marriage, you've taken some steps towards moving on with your life.
Coincidentally, I just did a review on my blog of a book which concerns ways to improve communication with your spouse/partner. I firmly believe that truly open and honest communication is the one key to keeping a relation strong (or making it strong from the beginning), and this book helps start the process. It's called, "1000 Questions For Couples," and although the title might sound a little trite, it might help to have a huge list of things (important things) to talk about other than your marriage problems and issues.
So while I agree that you should stop pursuing, when you talk with her, make sure it's NOT about your problems unless she initiates it.
