geeze BB... sounds like my Wife and her Ex. ^_- *thinks for a second...* Nah...
Well, passionate part, yes. But then work sets in, because you have to pay the bills. So you see each other less than you did when you were going out and wish you could go back to the wonderful times. When you get old enough to retire, you realize that you can't be that kid you used to be now that you have the time, so you both sit there and rot in monotony, wishing you had yours lives back to live again differently.
there you go. ;)
I'm thoroughly enjoying married life. :)
