What you CAN do to make yourself a better option is to be attractive, but IGNORE him.

Dress more provocatively, but go out and leave him behind
Talk warmly on the phone to others, then ignroe him
Buy gifts and do kind things for people, but offer him nothing

He will see a WARM person, but at the same time realize he isnt' getting any of it... he SHOULD pursue that if he IS a romance addict.

Dont waste time pursuing him or listening to his BS.. its just giong to wear you down.
