Truth is, you have no idea if she's been cheating or not, that's the problem. People who are in a relationship and active on dating sites only really scream bad news, the fact that you made a fake profile and she said open to dating, dating doesn't mean relationship but casually seeing someone, I would be truly upset. She could have been feeling lonely BUT there is no excuse, If you don't want to seem psycho you could just change the story up a bit by saying "your friend saw her on it" etc. Best of luck x1THIS IS NOT RELEVANT ANYMORE

It will bite you in the ass when you explain how you found out about this. This will likely be turned around on you and she will be upset that you've been spying on her. Even though I understand your feelings I don't think this will makes things better.
I would keep my eyes open and see for how long she has this profile active and not make a big deal about this just yet. Maybe she is a flirt who likes the attention from many random men and doesn't really have the intention of dating others, she just want to seem available to get some attention.0THIS IS NOT RELEVANT ANYMORE
