I'm going to post a status about my cheating ex
Why would you post about your cheating ex?
I want to expose him.
Posting online about someone cheating on your will just backfire. You should keep that personal stuff to yourself.
I don't care, I want him to feel bad
I think that you are hurt and wanting to get back feels good now, but it won't in the future. You should seek our support and try and move on.
