After all that you've given him, I'd say -- you have a job -- you pay for your own wedding! He's over 18 and beyond your legal responsibility to take care of, and it doesn't sound like he's appreciated anything you've done for him. If you had some extra money and chose to give it to him as a gift, that would be one thing, but from what you describe, given both your situations, you owe him nothing.
