Does he think I'm playing a game.. hes following me everywhere!?

Ok, for Sam, if you were interested in him, then why jump to another man to make Sam uninterested? Yes that is playing a game! Also, With your stalker, you should really confront him and tell him you are not interested in him, since there are several things you already pointed out. This will let him know and you will not have to worry about him following you and he will just move to the next girl. In a sense you teased 2 guys and one became persistant while the other saw you were just playing games..sorry to say. Hope things work out for you!
