Same here. Been together over 30 years, both early 50s - 2 grown daughters left home. Yeah it's not been a breeze for the 30 years we've been together, but there have been many more good times than bad. We have been through several difficult patches for various reasons, including finances, and deaths of parents etc, but come through the other side, and now have the best marriage! Do lots of things together, laugh together, travel together, go for meals and day trips together. Been very happy for many years now, and financially secure/solvent for about 11-12 years. Mortgage free.
Yes he can get on my nerves now and again, and I on his. No-one is perfect and no marriage is perfect, but I wouldn't want to be without him, and like a few others on this thread, I look forward to growing old with him, and meeting new grandchildren, and having the best life. And it's nice to have someone to share the financial and mental load with, and life's trials and tribulations.
I don't think this is a 'brilliant thread' as a pp said, I think it's desperately sad. Sad that so many women are just sticking with a man they hate, and have seemingly hated for many years, with this countdown to when they can leave. We are not in the middle of the 20th century - you don't have to stick with a man who you are not happy with anymore. Why have these women not left YEARS ago if they have been so unhappy, and hated their husband so much for so long? 
And don't under-estimate how hard it is being alone. Women on here champion being alone and how wonderful it is, and how they have the remote control to the tv to themselves, and the bed to themselves etc. (shocker: me and DH have a remote control each, AND have separate beds and separate rooms.. Have had separate rooms for 12 years. LOVE it!)
But whilst these newly single women are apparently living their best life, there are many more single women/women who have left their man or had him leave her, who are very lonely, struggling with everything in life, and are on the bones of their arse, without a pot to piss in. Either scrabbling by with state benefits, or fighting for every last hour at work to get money in to pay the bills.
Being with DH gives me security, comfort, happiness, and financial security. We don't go without anything, we manage to save multiple 100s of £££ every month, and we have a nice big savings pot should we lose our jobs. You can ask what if he leaves YOU, but that is very unlikely to happen. He knows which side his bread is buttered. 😁
tl;dr I have no intention of leaving my husband.
And before anyone decides to bash me/call me smug etc; I am entitled to post my views and opinions - just like everyone else is.
