Well, I know you're hurting but I don't feel that you give your wife enough credit.
Anyway, there is no way around the hurt. You can handle this.
Again, the work you've done is supposed to be for you. You don't fall apart now. You stay strong and you stay rational. That doesn't mean you can't beat the sh*t out of a pillow but if you revert to some hostile, aggressive version of yourself, then this has all been for nothing.
Be you. Be cool. Take it one thing at a time. I get that you wanted her to have an epiphany and appreciate you and come running back, but that was an unrealistic and unfair expectations. You're both going to deal with the consequences now.
