I'm sure it's been said all ready (i'm new to this thread) but know that you are not the one that is being proud, she is. She cannot accept the difference of opinions.
You can continue to put up with this behavior or decide to move on with your life. I doubt your wife is going to change (based upon what you have described). There seems to be so much bitterness in the relationship that that anything short of you becoming a fully dedicated JW again won't change anything. If you are able to fix your relationship it will be because you both find a way to "agree to disagree" and leave the differences aside. If she cannot accept the differences (the same goes for you!) then the problems will continue. The fact that she continues to flaunt the JW lifestlyle all around you could be a dealbreaker.
I wish you the best. Tough choices are never easy.
