I feel your pain. 3 years ago, after 13 years of marriage, my DH asked for a divorce. He was unhappy, not sure what he wanted, and we had been through a terrible last few years. I gave it all to God, prayed harder than I ever had in my entire life. We even had papers drawn up and I signed them. They were never filed. We just had our 16 anniversary last week. And while things are not great, they are better than they have been in a long time. He's still confused and unsure of what he wants, but we talk and he tries, and thats more than he was willing to do years ago. You have the biggest ally by your side that you can possibly have, God. Be strong, and follow where God leads you.
