Basically, this happened, some intuition told me that my girlfriend (well, my ex now) was doing something dishonest. I found out that she posted an ad on craigslist in the women seeking men section. I pretended I was somebody else and emailed her just to make sure it was her. She sent me her pic and it was! Now I confronted her about it, and of course it didn’t go well. We were having problems beforehand and its kind of rocky, she claimed she only did this to seek advice from men. Her reasoning for posting in that section was so men can actually reply. She said she was totally not cheating even though I said it was. Then she called me shady and deceitful for pretending to be someone else and tricking her!! I’m just really hurt and mad right now. Who is at fault here? Is she really cheating? Even though its not physical, I’m sure there is such a thing as cheating emotionally.
