Believe MLC is the sitch

I would have been disappointed if she had not.

You're honest with yourself, that is good.
Setting yourself to be dissapointed is bad, don't do that; you sent her the note.

Got mens health and rolling stone mags for effect (as well as reading :-))

Props work better in movies. Just don't leave your Divorce Busting book out, where she can accidentally see it.

I am a little afraid that she will take the improving me as either a ploy or that I do not want our M to work.

It will be seen as a ploy, until time proves it otherwise.
Well as for the other part...the changes you make are for you, and going back to the old you was part of the problem in your marriage, the old you.

wait until I take the kids back to let her think about it for the weekend?

If you are expecting her to have an epiphany over the course of a weekend...well buy something on the way home Monday to soothe your sorrows.

Am I laying it on too thick with the cake and pancakes? Why am I so insecure :-)

Are you? Be consistent.
You are insecure because you're world got rocked and the things you thought were absolute aren't anymore. You're insecure because your wanting validation from your wife, and you cannot control that.

Control yourself, the only thing you can control and you will be fine.
