Sometimes Miss, CDing caused my divorce, too. She couldn't be married to a crossdresser. She said so.
It's highly arrogant for other people, who don't know me, my ex, or anything about our marriage, to know what did or didn't cause our divorce. Yes, many gg's say it was the lie, but that doesn't mean it's always the lie. Sometimes it's the CDing. To the "it's the lie" pushers, you can't cookie-cutter this.
To the OP, we can agree on one thing, when you said "I just don't get it". You're right, you don't. Many threads over the years on the "reveal trap" explain it well.
