I'm Dating My Best Friend's Ex-Husband Am I Wrong?

I had an interesting conversation today with another co worker and I wanted to share it with you ladies. My co worker has been secretly dating her bestie's ex husband/kids father for over a year now. Well recently her bestie caught her red handed with her ex. My co worker was clearly upset not because she was  wrong for not telling her bff about what she was doing, no this fool was UPSET because her bestie told her she was wrong and she violated the "THE FRIEND CODE" she asked for my advice and I gave it.
First PERSONALLY if you're my friend you are my friend. I would never doing anything to cross you, hurt you or disrespect you. Real friends don't sleep with each others men PERIOD. Past, Present, or Future! 
Dating a friend’s ex takes BALLS!  I would never encourage sneaking around behind a friend’s back with their ex boo. Regardless if it was serious or not you're friend will look at it as straight betrayl PERIOD! Remember the saying "what happens in the dark always comes to the light?" TRUST your dirty little secret will come out and you're bestie will be the one thats hurt not because you were sleeping with her ex but because you were her FRIEND  she confided in you and trusted you. The whole time she's thinking her bestie has her back when in reality you're somewhere laying on you back getting banged out by her ex boo! That's not cool.. You know that chick Karma yeah she's a b--ch and whatever you do will eventually come back to bite you in the ass. If you love and value you're friendship with your bestie stay away from her exes EVEN if she says its cool decline the offer remember chicks before d--ks!
Now I know it's some trifling friends out there and some of ya'll YOLOING right now. So if you’re going to date a friend’s ex, you have to be able to look your friend in the eye, tell them you’re now the new person in their ex’s life, then be willing to get your ass stomped out for being trifling. If you’re not willing to accept your fate, you probably don’t like your friend’s ex as much as you think you do...
My advice do unto others as you wish others to do unto you...
Anywhoo that was my advice.. Who else wants me to help the solve a problem? Inbox me a question and I will answer it to the best of my knowledge here in the forum and it will all be anonymous!
Love and Peace!
