Portia,
It is normal to feel the way you do. You've got a lot on your plate and the stress/tension are not helping.

I would continue as you have been. I'm glad he at least has contacted you and not totally let you in the cold. Keep your expectations at zero at all times.

BTW, I'm sure he's told his family that the two of you are friends still. It's difficult to say how he would explain the relationship he has w/you except to say "we are just friends".

Please take care of yourself. Leave him outside to swing in the wind for a bit.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
