Can you see yourself taking down the "just friends" sign if he's nice with you again, or do you have a wall you're determined to keep him out of.  I'm nicer to my single female friends and talk longer not because I'm an ambitious pig, but because the 'happier' girls have set their parameters, there's nothing new to really explore.  It's a hard, mean question to ask yourself, but "how am I worth his time and energy? What can I do to calm his stress, not add to it?"
