I think you perhaps need to accept that you are living some kind of parrallel life with neither of you wishing to spend time with the other. If he doesn't want to go anywhere with you and describes suggestions of doing so as nagging(horrid word) then you need to go out and make your own social life. There is lots out there and you don't have to just sit resentfully wishing your life away. If you are invited anywhere as a couple, tell him about the invitation once only. If he moans and grumbles, don't tell him again, accept the invitation but tell the hosts that your husband won't be there because he is a miserable old git. Then when the evening or afternoon arrives, go out tell him you did not remind him as you don't want to nag. Put on your coat pick up your car keys and get on with your life.
