A: Yes, in fact he does like you. The *hint* here is that he started mocking you when he seen you conversing with another guy. Jealousy many times is an emotion that is associated with the protection and gate keeping of a love interest. Therefore, the signs are clear as day here....Cheers!!!
A: Well it sound like you might be giving this guy too much importance and attention as the result he is just playing with your emotions and enjoying your interest. Therefore, I recommend that you step back and do not show interest towards him and let him come to you...Cheers!!!
