My wife pretty much gave me the same reaction when I finally opened up, and when I did finally open up I couldn’t hold it in any longer. She said she married a man and not a woman and I couldn’t disagree with her.
I didn’t really attempt to deceive her all these years, but in reality that’s what I did. I also was deceiving myself, too. It has taken time, but as I think I’ve said before, we are generally kind to each other and help each other out. I can’t say your relationship will improve as mine did, but all I can say is be sensitive to how this makes her feel, try to be understanding, and by all means continue to show your love to your wife and children.
