Sorry to hear you are having a bad morning. Dealing with D stuff is difficult but hang in there and be strong for yourself and the kids. Focus on what you can control...You!! Look good, be happy, live a better life, etc.
The MC is likely going to be tough as well. You are likely going to hear comments from your wife that will hurt. Be mentally prepared for that and stay positve. It is good her IC is pointing out how destructive her behavior is. I wish someone was telling my W that. Keep in mind that is your sitch, MC is a very positive thing. At best, it may help your W better understand what she is doing to the kids and the family, and if she comes out of her alien shell, what she is loosing, you. At worst, it may help smooth the D process and help define how to move forward in a civil manner and in a way that will not hurt the kids.
I am starting to feel like the two of us are on our own little DB island...has everyne else from the community left?
