In which case I suggest you back off a bit - if you contacting him stokes the fire and he either ignores it or gives it the big FO then I would suggest that, however difficult it is to swallow, it's doing more harm than good.
The definition of madness is to repeat the same action and expect a different reaction - this isn't working so try something else: personally I'd write a letter, letting him know you love him and you want to be happy, that you're there fore him whenever he wants, and then just leave it. No good will come of repeatedly trying something that just makes the situation worse....
