When someone says he loves you, does he really meant it? Is he willing to sacrifice for you? Or does he just treat you as company when he needs it and when he doesn't he don't think of you at all. Will he stay up till the dead of the night just to make sure you are alright or he would rather sleep? Does he wants to talk to you infinitely until one of you dozeses off you he would just sleep when he's tired. Does he matter that you are the last person he talk to before he goes into temporal death and when he is revived are you the first person in his mind? Is he worried about you all the time or does he only worry when you have a problem? Does he make sacrifices just to see you smile? Or he just does nothing and claims he love you. If all these can be answered with an honest heart and mind, then you'll know if he really loves you.
