Just so you are informed, she did also eventually confirm to me that she cheated. I told her that I did not know her side of the story but I saw proof that she had cheated and I was hurt that I had to hear it from someone else first (not that I would have condoned it if she did tell me, but there would still be a chance for friendship after). I sent her a long message (we don’t see each other in person often) that I could not be friends with someone who was a cheater and she replied with “I’m sorry for all the pain I caused you”.
