I know I said I was away but I had to jump in here real quick.
STO, you are a good guy and whatever you decide to do is obviously entirely up to you.
I guess you have to weigh whether cheating at the age of 50 and after (I am guessing but I think 25+) years of marriage is worth it.
Chris Rock had an interesting rant about this.
It was called: Your Woman vs. New Pussy or something like that.
He said something about New Pussy doesn't yell at you to do the dishes or take out the garbage or mow the lawn.
But he also said that New Pussy won't take care of you when you are sick, be with you on holidays, cook you your favorite dinner and a whole myriad of other things.
Remember, when your 75 and retired:
If you cheated and got caught - would it be worth it when your all alone and thinking about how you screwed things up to go after that hot chick flirting with you at the copier machine.
If you didn't cheat - You can look over at the person you grew old with while your grandkids ask you how you and grandma met.
Of course it could be indicitive of other problems as well.
Whatever you decide to do, I'm sure it will be the right decision.
Just thought I'd throw my 2-cents (or a whole money bag of change) into the mix.
Sorry for stepping on your loquacious toes Lixy.
I'm off to go hide in my cave again.
