Not exactly sure what you mean by "legitimize them by having knowledge of them spread", but it's always better to keep relationship problems like this as confidential as possible. Everyone knows there's always two sides to a divorce/breakup. There's no sense in trying to make the other person look bad or try to convey yourself as the "victim". That makes the possibility of reconciliation more complicated and at the very least can damage your integrity.
"It is curious that physical courage should be so common in the world and moral courage so rare." -Mark Twain
