Hi, I'm the one that posted this FML. I know that cheating wasn't a good thing to do, but that wasn't the point of the FML. Had I simply found out that he was cheating with someone else, of either gender as I knew that he was bi when we entered the relationship, I would have said nothing. The reason I posted it, and the reason I do consider it to be an FML is because of the absolute ridiculousness of the fact that we were cheating with the SAME PERSON!!! The three of us have spoken and decided that none of us are going to continue seeing each other. The BF and I were obviously both deeply unhappy, and the third part took advantage of both of us. Ex and I will probably remain friends, and chalk this up to one of those errors in life that are hilarious five years later, but hurt like hell when they happen. #3 can go to hell for all I care
