You know, I see this in my X right now. He's 50 and is exhausted most of the time. He works A LOT and when he gets home, he's home to stay.
I, honestly, couldn't imagine him bar hopping anymore.
After bd (4 years ago) he tried to party, went to a few bars...but then just stopped. He doesn't drink and told me when he looked around all he saw were lonely people. He would NEVER have saw that 30 years ago. Sex drive in high gear and it was exciting. Now it would be a challenge.
