What It Actually Means: She is most definitely not fine. In fact, she's about to punch a wall.
"Here's a basic rule of thumb: If the woman in your life uses the word ‘fine’ to describe how they feel about something, they almost always feel the opposite," says Eric Resnick, dating coach and owner of profilehelper.com. "It’s one thing if she tells you that she's good, or even OK, but 'fine' always seems to have something hiding behind it. Guys take their partner's words at face value, causing them to miss the chance of fixing problems before they become relationship crises."
