I have this guy friend who I have known for five years... we are best friends, share everything with each other (no secrets), enjoy each others company more than anything else... but we only really do stuff alone together... whenever I invite him out with my friends he says that he is too shy and that it will be awkward... all the while I'm saying "hey, im shy too, and you will love these people, they are nice and will accept you instantly"... still doesn't want to go... is he really just shy or do you think that there is another thing going on here?
