My advice would be to try to keep your eyes wide open and to not look back to what was and to listen to what is really being said, rather than what you think is being said or what you want to hear...if you don't you could miss out on the chance of a relationship that will truely make you happy and not be full of contradictions and uncertainty.

Oh, and try diverting all his calls for two weeks...whilst eating lots of Ben & Jerry's ice-cream....when/if you decide to call him back, casually remark that Ben and/or Jerry was stealing your time...
