history: I recently found out that a good friend of mine has been cheating on her fiance with multiple different men for years. I was aghast and horrified that she would behave this way and even more upset that she tried to justify the behavior. I recently found out a good friend of mine has been cheating on her fiance for years. How awful! how do you feel about it?
current: Very angry and frustrated that she would behave that way. It makes me think less of her as a person.
next: Yes I understand, it is really sad when you find that people you have known a long time can be very different from what you thought.
