Most Helpful Guy
be yourself: you want him to like you for you,
work on you weakness: do this so you can be the best you, you can be! also in case he doesn't feel the same way about you, you won't care as much because you feel better about your self and feel more confident.
smile at him: this will tell them that you interested. you may not believe this but by you not ever looking at him he may think that you don't like him.
be read to be disappointed: there's a good chance that he won't feel the same way about you, so don't get you hopes up. stay level headed.
stay open: he is not the end all be all guy, there are other men out there that will be better for you.
LOVE: google the definition for the word "LOVE", then think.. "do I have those on paper feelings for him" if the answer is no then you don't love him you just like him. be careful with that, because if he is a shitty person he will use your feelings against you to control you.
MAKE SURE HE IS WORTH YOU FEELINGS!
