Choosing to keep 1 small gift and giving back the rest would make it easier for both of you.

In fact, it would be best if you could get back to home sooner than he, so that you could "help" him pack some stuff or whatever. So that he understands how serious it is for him to make a life change. It is a life change for him.

While he is manipulative of finding ways to stick around, also think he is finding not easy to move on. But now, your influence so far, is not helping the situation.

So have to modify your actions.

Best of luck. Just hoping your start of 2010 won't be too painful.
