I mean no offense, but blaming your wife's behavior for not clearly communicating with her is going to get you to the big fat NOWHERE.
I understand your hurt with her actions, but this is actually an excellent time to draw the line in a bit. Telling her how you feel is going to make you feel vulnerable, especially if she doesn't react the way you hope she will when you tell her how you feel.
But great rewards require great risk.
You've been hurt before and you know you can get over it.
Timing is important, yes, but EMAIL can be your friend.
