Sophie,
our situation is so much similar...

They leave you hanging with one thread isn't it? And the moment you say "I give up" they come back.. oh but I was thinking about you... I missed u so much... !!

Sometimes makes u wonder if they are just testing your patience.... they know u love them too... ughhhh !

Here is a deal - Give him "sense of loss" - he can lose you too !! ( and not calling not answering isn't giving him that!!) --- At least you will come to know -
