[Candy Sha]

and we usually hang out and everytime I see him And one day I saw him and his friends talking and his friend saw me and whispered and my crush was smiling and happy and my crush came over there and talked to me But when I'm with my friends he doesn't say crap to me but when I'm alone or I say something to him we talk alot. Well I want to know if he likes me and btw he's my ex and his friend teases us about it and hes like wats going on between yall and hes like yall should work on it. is there any other way you can tell?Thnx
