If guy doesn't want a relationship believe him. What he wants is some roll in a hay. If you aren't going for it he might settle for some other physical things. But he clearly isn't considering you for a serious relationship. When I was your age I would probably not think twice and just go along. Looking at it now I think it's pointless. I wish I knew better. Staying with guys who aren't into you will prevent you from meeting the ones who want to be serious.,
