“It’s all right to love someone who doesn’t love you back,as long as they’re worth you loving them. As long as they deserve it.”
I cannot agree with this. They may be worthy of love as a person; them not loving you back does not make them innately bad. But it is not all right, because someone who doesn’t love you back probably never will, and love that isn’t reciprocated is one of the crappiest things there is. And in that time that you spend loving them, you waste time you could have spent loving yourself. And loving yourself often leads to someone loving you.
