I like a guy and i have been continuously telling him that i like him, i send him cute GIF and i asked him out on a date. We started talking in February but since 3 months now he does not reply but only reads my message (basically when he understood that i really like him). I told him something and surprisingly he changed his profile picture accordingly. I don't know if he will come for the date. Do you think he knows that i like him? is it that difficult for a guy to express how he feels?
