Do what he asks... i'm serious. Chances are good he's wondering if he really wants to be with you. So do it... Don't talk to him as much. Don't see him as much. When you guys DO hang out, don't let it get to sex every time. These will take a lot of self control on your part. But i think you can do it.
Basically, LET him miss YOU.
And if he decides to move on without you. So be it. You sound like a cool person. I'm sure you'll have no problem finding someone better.
But i'm guessing after a few weeks of his own medicine, he'll be begging for the same old contact. Just don't give in too soon.
"We are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically.
That’s kinda cool! That makes me smile and I actually feel quite large at the end of that.
It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us."
