1. Make sure you are not dating him just because he is a sad boy. Make sure you are not dating him out of pity either. Date him because you like him, sadness and all.

#2. Do not expect yourself to be able to fix or save him. Be prepared to love him as he his. He may not ever become less of a sad boy. Make him smile when you can, keep him from being alone. But don't try to be his rescuer, or his savior. Help him keep it together when you can, and let him break on you when you can't. Do not try to change him.

#3. If he has physical scars, kiss them. Run your fingers across them. Tell him you love him and his scars. Not for them, not despite them. You love his scars because they are a part of him, and you love him as a whole.

#4. Do not feel guilty if you can't stay with him anymore. If it becomes too much, if you just fall out of love. If you just can't see yourself with him. Do not blame yourself, do not hate yourself. Just let him go as kindly and cleanly as possible.

#5. Do not hate him if he leaves you. Remember sometimes things end. Do not try to convince yourself that he needs you, do not hate the next girl he dates. Do not go to her and try to tell her how sad he is, how he will destroy her with his pain. Because we both know that isn't true, not really. And it isn't for you to decide.

#6. A warning. Relationships with sad boys rarely last, even if you think they will. He isn't your patient. You aren't his angel. This isn't a story book where you'll put him back together and he'll love you forever. If, by some miracle, you do manage to change him. If he becomes happy and "sad boy" becomes a thing of the past. Do not be surprised when he leaves you, because chances are, if he's truly changed, he will.
