tell him or you will lose him(best friends)

ok so if you and your friend flirt alot and are close look at how he acts around you and compare it to how he acts around other people if he treats you in any way special or tells you that your hot,kisses you on the cheak or if he/she has ever kissed you on the lips even playing around their is a chance that they have feelings for you so act like your playing around and on a note or text write do you want to go out with me and wait for there responce you cant lose!
