What are the signs that your boyfriend could like another girl?

If he seems distant and is suddenly too busy to talk or hang out with you, that's a sign. If he talks about another girl, to his friends or even directly to you, that's a sign. Another pretty good sign is, well, he's a guy. Many girls believe that guys who take an interest in them suddenly go blind and are no longer attracted to other girls. Teenagers -- guys and gals alike -- would do well to stop pretending that every relationship (I use that term loosely) they have is an exclusive one. The idea that two young people must "break up" and stop seeing each before they can date other people is silly and, at the end of the day, destructive, leading to all sorts of teenage angst, heartache, and other negative feelings and destructive behavior.
