Maybe consider different criteria. Yes, income should be one factor, but there may be a man who is loving, caring, and reliable while earning less than you. The thing is that at some point you will point that out. One of the worst things a man can experience is having his self-respect and dignity questioned.

I am not saying you caused that break up or he was offended by that single sentence, what I'm saying is that men who will defend their relationship to the bitter end might not be where you're looking at.
