Hi Nanabird. You are in a situation that, sadly, is not uncommon for many reasons. You haven't established the reason in your case - as LuckyGirl says, it could have been an affair, or drugs. Whatever it was, it affected him enough to want a divorce. Have you never been able to find out - after all these years? From my own experience, our sex life ended 15 years ago, suddenly. He just stopped wanting to do anything, although was always kind and affectionate. I tried talking about it and saying how unhappy and rejected I felt - it only made things worse as he felt under pressure to "perform" and guilty because of how I was feeling. In the end I settled for what is a lovely close relationship without the physical intimacy. It's great if you still have that in your 60's and 70's but not essential - indeed, I have a friend who is the same age and has the opposite problem! I often think that statins and depression after the death of his mother played a great part in the libido loss. Then, as the years go by, they lose confidence and it is so true, if you don't use it, you lose it! However, I have learned to count my blessings as we have a great life in every other respect and are great and loving companions. He also has very early dementia, which fortunately has stayed about the same for 3 years, but I think that the brain plays a large part in all these things. Your case is somewhat different because of whatever it was that happened when he was away. If you can't talk about it and you are now happy together, then move on and develop what you have. Or move on and find a new relationship. There's a lot more to happiness than a good sex life and, nice as it would be to have both, there are so many women who are in the same boat, you'd be surprised. All the very best of luck and, if you can, talk about how he is feeling and what happened all those years ago. If he thinks there'll be no blame or guilt involved, it might really help.
