What is the worse relationship advice you've ever seen someone give in person?

"The best way to deal with an adversary is to face it."

Spoken as if the whole reason it's an adversary is you can't trust yourself with that.

Be the submissive wife and be joyfully available...

My dad told me that I should date a man for at least two years before having sex. He said this when I was a 40 year old divorcee. And he really wasn't a man who had any business giving advice on romance or morality.
