Here is the link to the original thread. The guy states in his post that he has a girlfriend so he wasn't looking for anything with the GW girl. But he had a crush on her. So after he confronted her, she cut contact. She decides to explain herself here.

The two discuss the reasons why, which is hard to follow. Then other people start adding to the drama. The girl gets really defensive when someone agrees with her for cutting contact as he was flirting while he has a girlfriend. It is a juicy exchange, and she admits that he was overzealous as they hadn't spoken very many times before he saw the pics.
