If you say you like him, even if he rejects you, it is nothing to be ashamed of, because in his heart, and because of your action, he will feel gratitude towards you.
(Dunno)

If he says he like you, be sure to tell him your feelings, like is like, dont like is dont like, never ever be afraid to hurt him and hesitate, dont let him wait till the end of desperation, because a guy's heart, once broken is really hard to heal.
(True)

Guys have their own pride, is because of their love for you that they give way, dont be stubborn, sometimes their decisions may be logical.
(True)

If guys throw their temper at you, it is because they love you, treat you as their closest, dearest, most secure person, dont ever challenge his anger head on, patiently wait, till his anger subsides that he will hug you with full of regrets.
(Might be true)

If he prepared something for you, even if it doesnt look good, is simple, do treasure it, because it is filled with his thoughts of you through the night.
(Definitely true!)

Believe he has given you a really really wonderful life, give him encouragement, because it will motivate him to create a miracle.
(True)

Dont ask where he went, instead tell him to be safe, and you will wait for his return.
(True)

Dont always say ~I Love You~, he will treat it like jokingly saying you are mad, however do not not say it as well, because at times, guys might need this statement more than girls.
