Wow, great responses!
I didn't really know before I started checking his email. I would get anxious, look at his email, catch something a littlle off kilter, and he would make some excuse which I believed. Ultimately the emails were made me see who he really is.
There was no other way to really know. I now know he cheated on me and is capalble of manipulating. I want to know if he is manipulating this other woman or trying? Was he trying with me, or just manipulating?
