I CHEATED ON MY BF WITH HIS FRIEND & HIS FRIEND KEEPS TALKING ABOUT HOW GOOD I AM IN BED!!!!!!!!!!!!!!!?

Consider this a learning experience and let it go. I gather you are still young and need to make wiser decisions next time. For now, you have to accept and deal with the consequences of your behavior. Sadly, the person who has been damaged here was your ex-boyfriend. He too will learn from this and hopefully not feel that all woman cheat. This is not being mean, but truthful. Take your losses and let him move on. I tell you to let him move on because IF he were to take you back, it will never ever be the same. He may not trust you again or he may make "mistakes" similar to yours and you will not be very accepting of it.
