Okay, ladies. We’ve all been there. You’re totally into a certain guy, and things seem to be going well, but you’re not quite sure how serious he is about you. Little things start to make you wonder if he’s not as interested as you thought he was. Maybe you brush them off and scold yourself for being too insecure. Maybe he always has an excuse for his behavior. But in my experience there are five tell-tale signs that he’s not serious about you—whether he wants to admit it or not.
