"This is the most important thing to know before getting involved: Relationships are very simple. Only two things can happen. You get married or you break up. That's it. There's no third thing. Chances are you're going to break up.
"Take a good look. This might be it. Why? Because at some point that person's going to say something just a little too ignorant for you. Or they'll do something you just can't overlook. Whenever the person does that thing, it registers right away as something you cannot live with for the rest of your life.
"No matter what it is, it's okay to break up about it. Nothing is too petty to consider when the next thing you might have to think about is getting married."
