This is a general question. There really needs to be followed up with questions to this situation. Focus on the meaning as to why you want to expose the person. If it’s due to a crime or harm especially where children is involved you need to go to the proper authorities. There should be no loyalty over the harm of kids. So if that is the case, take a deep breath and expose the person. If it’s to get back after a fall out your motives may not be in the right place. Things in time will be revealed with anyone. So your willingness to expose the person due to anger or get back will come back to you. The old folks had it right when they said while you “dig one grave you might as well dig two.” Be clear on your why. Everything ain’t for get back purposes. I know Karma serves her dishes appropriately so you don’t have to let the way you feel push up her sentence.
I’m not saying don’t expose I’m saying be clear on your why. Be sure it’s for the reason of justice that is valid and not purely for the gain of making you feel better for how someone may have treated you. Exposing someone just to get back and it’s not for a real purpose of them doing something they shouldn’t have actually done is headache. Also be sure if you do expose them you have proof. This is not the time to interrupt someone’s life on a “felt like a punch” movement. Felt like a punch is a joke my college friends would use amongst us to say whatever was happening wasn’t really happening but we imagined it would had it gone down the way we were describing it. Don’t let that be you while you are focused on the wrong angle to approach the situation.
