MKAC - is this the time for tough love?
Look - you are unhappy and anxious etc. because he did not call AND you are afraid to call him to get reassurance because you think you will look stupid. You have ability (your adult self) to end the anxiety and be reassured. Which is worse for you-the scared abandoned part or the I might look stupid part? Screw your courage to the sticking place and call the guy. Let yourself do something that will help you feel better.

Now I am off to paint finger puppets for next week's therapy production.

MKAC - if too tough - then disregard.
