It doesn’t matter how much of a gentleman he has been up until this point. If a man you’re getting to know at a bar, on a date, or online says any one of these lines, run — before he breaks your heart, or gives you the overwhelming urge to slap him.
“I could never date a woman who earns more than I do”
So essentially, this man’s sense of self-worth, his sense of having an equal hand in a relationship, his sense of being a man completely goes out the window when your salary exceeds his. It wouldn’t just bother him a little to not be able to treat you to nicer things. He is saying he could not stand to have a woman make more money than he does. Forget if she is happy in her career: if it makes him unhappy, he’s out of there. Pretty selfish when you think about it that way.
