Never truer words spoken, unfortunately..
In my early 70s been their done that, I admire the men who have made it work.
I've never been happier been single. I'll never marry again. Everything is so much easier. (to each his own I guess)
If you're doing all the work to make everything work it will never work apart from leading you to and early grave.
Cut your losses, you won't regret it.
Live your life on your terms, don't stress over it every day.
If you need a bit of female company once in a while, well this is Thailand after all.
