Dating can be unpredictable. It's not unlike selling a car: You wonder whether the person you're going out with is kicking the tires with serious interest or whether they're just taking a test drive for the fun of it, with no intention of pursuing a relationship with you. But you're not just the seller -- you're the buyer. So you want to determine as soon as possible whether your date is worth any more of your time. If you spot any of these five signs, there probably isn't a love connection.
