<human>: Can you condense the text into a few key points?

Yeah you may have been his bit on the side for the past 8 or 9 years, but that's exactly what you always have been and always will be. It should have ended the moment you got engaged. 

You have a wonderful, loving fiancée who would do anything for you. He literally changed his life to be with you and yet you continue to cheat on him. You don't know how lucky you are to have him, no-one has ever looked at me the way he looks at you. You're too busy being unsatisfied by what you have to see how good you actually have it.

So when you called me & said you're pregnant & you don't know who the father is... I WAS SO HAPPY. I know I'm your best friend, but the whole time I was faking concern... I was smiling & dancing & pouring myself a glass of wine.

You know how much I hate cheaters, you know how much I hate that fucking loser & tell you to stop it because I don't want to be part of your lies & yet you still continued to fuck around and this is the glorious result. 

I hope you learned your lesson.
<bot>: best friend is cheating on her fiancée & got knocked up by the other guy. I'm happy because karma.
