When a guy likes you, he will embrace you or touch your hand or leg while speaking to you. Take note of how he behaves with other girls. He may be a flirt if he touches them and acts the same way around them as he does you. However, if he treats them differently than you, then he isn't flirting with them. Here are some other signs that could indicate that a guy is simply a flirt: He smiles at other girls - Not every boy who smiles at others girls is a flirt, but if this behavior becomes a pattern, then he might be. Flirts usually have more than one girl they are paying attention to at a time while others wait for their turn. He talks about other girls - If a guy is talking about his friends' sisters or girlfriends, it could be because he feels uncomfortable when someone else is listening, so try not to take it too seriously. The same thing goes for him looking at other girls during conversations with you. If he is doing this a lot, then he might be trying to send you signals. He makes comments on other girls - Comments like "You look nice today" or "I love your hair color" are innocent enough, but if he's saying the same things to several different girls, there might be something wrong here.
