Some nasty posts on here about men over 60/65 saying they are all horrible. How vile. @madcatladyforever is seriously projecting their issues onto the OP. All I will say is that when past 50/55, some men can't be arsed so much with partying/socialising etc, and do 'wind down' a bit. But so do many women of that age.
I was all long road trips, long coach trips, partying til 2am, and going to shows and concerts etc etc (with DH and with the kids, sometimes all of us!) Right up to the age of 45-48. Then I got a bit lazy, unmotivated, and to the point when I couldn't be arsed. I preferred to stay in, watch TV, go to the cinema, attend a little art class, and pop to the pub but come back by 9pm. Fortunately, me and DH got this way at the same time...
We love nothing more than snuggling up on the couch, with a bottle of wine and a bowl of nibbles, watching a good film. No more travelling across the country, and not getting home til 1am after going to a concert, or lengthy coach trips. The quiet life for us now. Done all our globetrotting and partying and concert going. 
Seriously though, a 12 year age gap isn't that bad. And you could easily be a 'carer' for your spouse if you were only 5 years apart in age. Or the same age. So @BillySpain's comments are a bit daft really.
Also, I found it an odd comment that an older man will be controlling as he thinks he is 'always right.' That's not an age thing at all. Some people do talk such tosh!

You may as well just continue anyway OP. As women get older, we lose our beauty.
