Youre so busy trying to DO something. Many times, the best course of action is to do nothing. This is a choice, and often, a strong one.
why on Earth would you send this? W, you know I want us to be great again. I am not going to be able to go to the game tonight because I always seem to pressure you. Neither of us wants that. I'm going to take some time away to work on myself. Give the boys my love, and I will see you all tomorrow.
you know I want us to be great again. - yes. she does. why do you need to say it?
because I always seem to pressure you. Neither of us wants that. - yes. sending this note is pressuring her.
I'm going to take some time away to work on myself. - for you? or for her? and really...this ONE night is that time?
If you want to talk to your kids, you may consider something like: "I cant be at the game tonight. I'd like to call the kids XXXXX."
