I do understand that marriage is about compromise, my wife and I do it every day, but I stick by my original point. I went back and reread your post, but it only confirmed to me that while you may have been specific about women staying active, you are also very clearly generalizing and judging what men want from retirement.
Nowhere did I say there's anything wrong with women who want to be active. If anything, good for you!
But this statement "and best of all…..SOCIALISE! This is what most men balk at!" reinforces to me that you feel men are wrong for wanting to walk away from social activities. What he's doing now, "relaxing," could be what he's always dreamed of doing when his career was over.
Having said that, I heartily agree he needs to get off the couch once in a while and do things with you. And he definitely should be doing more around the house now that he has more time. Just don't judge him (or any men) for not wanting to do all the same things as when he was working.
