IS HE Just being friendly?

he might just like you. when a guy likes a girl, they are very nervous and confused about how to act and how they should come off and behave. he is just acting odd over that reason. he is so nervous and worried and thats why he is being that way. u can always lie and say you have a boyfriend if the topic comes up that he is interested in you, and if you don't want to go out with him.
