Of course mail him to clarify things. Well, after the second
mail - probably there are reasons why he didn't wish to reply you.
One good solution is to wait and don't bother too much. 
Broke about one year ago? Of course, its isn't easy to move on
without pinning onto some past eh? Sure you could try again - but
it has to start from friendship scratch again. Many things could
happen in a year and the 'new' him may not be the 'old' him
that you once loved.
