Please listen. I made the same mistakes. I doubt if my marriage will ever be saved now. Don't set yourself back as I did.
You are going through stages and will bounce back and forth between them:
Denial - this isn't happening, he will comeback, this is a nightmare
Bargaining - If I change this he will come back, etc
Anger - see your post above
Depression - you will lose weight, not want to eat, want to sleep, etc.
Acceptance - the faster you get to this stage, the better chance you have at dealing in a healthy way.
Please - at this time do not call or talk with him. Any request is going to make you angry - I know, I've been there.
"Good for him. Let him go have his slut and his "simple" bachelor life and run around without any f***ing direction like the rest of his family. I should NEVER have settled for someone like him."
He will realize the statement you posted above - BUT NOT IF YOU FIGHT WITH HIM, THIS WILL ONLY JUSTIFY WHAT HE IS DOING.
Please - you need to stop contact with him until you are ready to DB his a$$.
