Watch His body language
Your best clues to signs a Libra man likes you come from reading his body language. His body signals are far better indicators of how he feels about you than anything he may actually say verbally. The eyes are the biggest give-away. If he returns your gaze, and especially if he holds eye contact with you longer than you'd normally expect, then chances are he’s quite interested.
Flirt Flirt Flirt
Another signs that a Leo man likes you is Flirt. Flirt. Flirt. He flirts with you to re-assure you he likes you. It's a means of keeping you interested and aroused, as well as letting you know that he is there for you.
Social and an enormous desire for communication and exchange of words, short messages, fear of emotions and feelings with possible emotional outbursts are also sure signs a Leo man likes you.
Trust your instincts and you'll 'feel' whether he's interested or not. Look for small gestures and tone of voice tell you a lot about what he feels towards you. If you pick up on any signs of rejection, don't waste your time on something that is very unlikely to happen, no matter how much you think you fancy him.
However, if the signs are there and the signals are good, it's time to make your move.
