Eric!!!!! I am so sorry you are having a bad couple of days. It happens to ALL of us!!!! Not that these words make it any easier...
I want you to do something!!! Start concentrating on everything good in your life and start doing it now. Every time you start thinking 'victim' thoughts and 'victim' feelings...pause..and think about something you are so grateful for. You are starting to sound like me...so I am here to shake you!!!
You cannot control your wife and your current marital sitch...you know this and I know you know this...but you do have control over the rest of your life. I know how much your work and family mean to you. YOU are letting this sitch effect your job and career. You have choices here and you know it. Start harnassing this negative energy and turn it into postive energy. Start committing to your work again...start committing to yourself. Your family is going to be OK no matter what happens. Continue being true to Eric...your children are taking in everything. You may not feel it right now...but they see this...and will learn from your actions..and will admire you some day. Stay the course!!!! You're not alone.
