Prematurely called divorce busted, worse now

[Orich]

Here is a question, how do you handle setbacks? I don't know how well my DBing is going, as I haven't seen any real reaction from W. One of her complaints about me was my bad short term memory. I don't know why it is bad, but it is. I guess she always saw it as me not caring enough to remember, or something like that. Last night we went food shopping with the kids. She gave me a couple of items to grab as we split up. I forgot to get frozen bagels for the boys to eat this morning. So, I get e text message earlier today asking where the bagels were, that I was supposed to pick them up and obviously I forgot. I typed back that I thought she had gotten them, then forgot about it by the time we got to the register. She said the boys wanted their bagels, and now they can't have them.
Is there something at this point I should do or say?
As long as I am posting, I saw my IC last night. He says I am carrying a lot right now, and that I could keep carrying it as long as I want, but it is ultimately going to do damage. He feels that I need to confront W and give some sort of time table. In other words, tell her to s**t or get off the pot. I posted earlier that she keeps saying the M is over, but hasn't pulled the trigger. I am going to say something to her this weekend at a time when the kids aren't around, or asleep at night. I admit to myself that I am afraid to do this, but I also know that I can't go on forever pretending we are a family. I still hope that her IC brings about a breakthrough, but I have to be realistic, I guess.
