MKB, I'm catching up on your sitch. Wow. I wish I could do something to ease your anger and pain. You do need to express your feelings, so I suggest writing them all down in a letter addressed to him. BUT do not give this letter to him. Keep it for yourself, and maybe someday you will have a chance to express this to him. For now, though, I agree with labug that only urgent matters should prompt you contacting him. Remember, only urgent matters. After the dust settles, some form of communication can happen--that has nothing to do with your R.
I know how you feel. I felt the same last year and early this year. The man you married, the person you trusted the most and who you thought would be with you for the rest of your life seems to have morphed into an alien. I remember the anger just wouldn't go away. I couldn't sleep. I remember being angry at anyone who seemed happy: couples, families. It was a generalized anger. It was bad. It happens to all LBS and to all WAS.
We're here for you. Vent through your posts, and write that letter. Just remember to not give the letter to him now.
