This won't last forever. When I was totally hopeless and feeling exactly the way you're feeling now my husband suddenly came back. We had a second chance but it didn't work. You may not want to give your wife a second chance even if she comes back because it could prolong your misery and the marriage could still fail. However, I strongly believe it's admirable to be committed to your marriage, to wait a long period of time for your wife to come back, to keep loving her and believing in her ability to make the right decision, and to have hope until the day the divorce is final because people can change if they truly want to. Obviously there's a higher chance that your wife wasn't as committed or mature as she should have been from the beginning, so she may be lost for a long, long time and it may be more humane for you to let her go, but I still believe that divorce should the last resort and you're doing the right thing by practicing DB and waiting to see what happens.
