navywife, I think you're absolutely right about acting as if. Right now he's really into blaming you and nothing you can say or do will make a big difference. Hopefully, time will clear his thinking and if you aren't rude or antagonistic, he might be open to reconnecting with you in some way.
I know this must be devastating to you, but you can at least tell yourself that you are wise enough and have good enough values and morals to have fought for your marriage. Continue to take the high road. Make your life as rich as possible. Who knows what the future brings? Rebuild your strength and sense of self. And remember, despite your sadness, this is his loss.
