I agree with 25years and CS about the FB thing. Get that stuff off the wall for good from this point on and either don't respond or make a joke. If you say "huh" she'll probably explain it which will make you think she REALLY must want to know about your letter and you'll cave and tell her.
I love the idea of making a joke out of it. Shows you haven't lost your sense of humor in a rough time and that there is some mystery about you.....
Nothing good can come of telling her.
Here's what MIGHT happen:
Tad: "I was going to send you a letter on our anniv. but I chose not to."
W: "What was in the letter?"
Tad: "Just stating that I really wanted to work things out and that I wanted to remember our anniversary."
W: "I told you I was done."
You don't want that. You don't need that.
And go to the game. Go to anything you get asked to go to. Believe me, it helps take your mind off things when you start socializing with people regularly. It's kind of hard to dwell on the pain when people are all around you talking about their own issues, being silly, laughing, whatever. Back when I was in your time frame I used to go visit family and say "can someone just talk about crap going on in their life so I know it's not just me who has issues to deal with?"
