i WAS THINKING THE EXACT same thing... giving him a taste of medicine. But the problem here is that i cannot resist calling him and if i dont call him, he will take it real badly meaning he will ask me in a serious manner "what is your matlab?"
There seems to be a deeper issue then the friends ther.I would suggest you not calling him everyday.Wait for him to call you too as you should not come across as the one desperate for his attention.You can be all "busy" too.After he gets the taste of his medicine, have a serious discussion with him.Make sure you both lay the ground rules etc for your relationship.
