I hope you're feeling better today, and it is amazing how you get what you need when you truly need it, isn't it?
I know it's easier to say "don't worry about the next couple days because you can't do anything to control your W's actions" than it is to actually do it, but I truly hope you can. I'm sure your C can give you ideas for coping if you ask him at your appt. today. I am so glad that you can see the progress you've made in IC- that is big and will help you whether you stay married to your wife or not. I've been seeing an IC also, whereas my H hasn't even begun to take a look at himself and I have very little hope that he will. (He keeps placing all our issues on me, and cannot accept responsibility for his role. Very frustrating!) And it is a positive sign that your W is even going to the counseling sessions- I hope you are both going in with open hearts and minds. We stopped our MC last week when we realized that we were just not ready to open ourselves up like that.
And please take care of yourself in the meantime- you deserve to be good to yourself.
