Don't have any spells for ya, but I do have a something else you can try.
Get yourself all prettied up, talk to him, flirt with him, make jokes and laugh a little. Be yourself around him while showing him how you feel. If he doesn't get a clue then you can try being a little more upfront or even just tell him flat-out how you feel. If he can't accept you for who you are or doesn't feel the same way about the real you then you may want to consider moving on and finding someone else.
