My husband told me that he was miserable several times before he began to withdraw completely
. Thank goodness I didn't let that stop me. I kept right on working on the marriage (by myself, since he wasn't interested at first.) Eventually, (though commitment and lots of effort), I was able to not only save the marriage, but make it stronger. So, it was very much worth the effort. You can read a very personal story of how I saved my marriage on my blog at http://isavedmymarriage.com
