Let me rephrase since I didn't think of this in the context of a MLC Male.
It's true, I'm a normal Man, so in that context, I would lie, deceive, and conceal. I certainly would cover all my tracts to the best of my ability and under no circumstance would I introduce the W to her. That would preserve the excitement of the affair. MSTBX hid her EA until I stumbled on to it and even then She couldn't face the reality of the damage it caused to our family. I always thought She was in some kind of MLC, but maybe I was wrong. After I discovered it I really started to distance myself more from her. Maybe in her warped mind, she was protecting my feelings by concealing it, I don't know. I do know that after I discovered the affair She started to loose interest in this OM. I've heard from her Family members that it's totally over, but I don't know and at this point it makes little difference to me.
I stand corrected, add a little MLC and the behavior could even be more mischievous. I'm not sure what I would hate more, pushing it in my face or hiding it from me.
