I feel for you and wish I had an answer. I too am very very lonely. I have been married for 37 years. The last 20 years or so have been lonely. We hit a rough spot way back then and nothing was ever resolved. I have kids which made it impossible (in my mind) to leave. Everytime I bring up anything that I believe needs to be resolved he either gets angry or shuts down. It's pointless. I have been unemployed for years because I had family obligations that needed taking care of. I rely on him financially. He is retired. He is always around. It wouldn't be so bad if he interacted, but he doesn't and I no longer know how to engage him. I have pretty much given up trying. The computer, tv and his books are his only interests. As an aside he suffers ED. It is strictly situational/psychological (been tested) . Sorry I couldn't help. I just needed to rant.
