I cheated on my boyfriend with my now dead best friend
Well, that's sad to hear, are you satisfied with having cheated on your boyfriend?
Yes, I don't regret it. He was a cheater and bailed on me when I needed him most.
He may have been a a bad boyfriend but cheating is still wrong. Instead of cheating you should have broke up with him.
It's not like I did it on purpose. It was just one night stand thing.
No one accidental does that, cheating is always wrong and I hope you learn that in the future.
