If he misses you, he'll call just to hear your voice.
If he wants you, he'll say it.
And if he cares, he'll show it.
If he has a thought about you, it will come out of his mouth.
If you are on his mind non-stop, he will do anything he can just to see you.
If he truly likes you, he won't let anything get in the way and fight back just to keep you in his arms.
If not, he can't be worth your time because you're obviously not worth it.
