Yes crossdressing is one aspect but the lies that go with it isn't. Trust is another building block but when I wife is told years down the line that trust is shattered.
Yes this does happen and most times it happens because the cder pushes things to much, and basically it becomes all about the cder.
I am one of those SOs who after years of everything being ok, I gradually hated the cding, why, because Nigella came out of the forces and went a bit wild, dressing more often, buying things that she didn't need and clothing that she would never wear, it became all about her. Fortunately for us we worked things out.
Just don't try and load all the blame onto the SO.
