I can't even read posts in SSM anymore as it further depresses me. Some of those folks have an outside chance in hell, because their spouses are making some attempt. There were times when your H did make some effort and it has stopped again. I know how hard this is on you, I've lived with the rejection and pain and know how it makes one feel.
Marriage still takes two and you can only beat your head against the wall for so long before you stop.
