Don't be a snitch. I also have it if in case I get bored of my gf or if we get on a fight. Don't you dare 😡

Swipe left. Either his wife already knows about it or he is really really stupid and if his wife doesn't know that he is really stupid then well she is even stupider.

Nothing at all. Not your business.

What should you do?    Nothing

And keep on doing it

Stay out of it, I'm speaking from experience here!

I found out my cousin was cheating, she had a picture of her sucking on a guys tongue on faceook! I informed her boyfriend of this, and it sunk him into a massive depression, and when he learned she was pregnant, he killed himself. I know depression is a chemical issue, but I feel that I played a role in all of this by letting him know she cheated. If I had a do-over, I would have never told him about it, who knows, maybe he would still be alive today.

You are not close to these people, and quite frankly its not your business! Learn from me, its much better you stay out of this. Trust me the lowlife (your buddy) will get his karma, it just won't be you who serves it to him.

Nothing.... Forget you saw what you saw and move on.

have casual experience with him
