First of all, you give me hope, of which I have none right now. You are a sliver of moonlight on a very dark night.
Second, I think if he did call back, I would just hang up as soon as you realized it was him. And keep doing that. If it keeps up, change to a new private unlisted number. Maybe call the phone company and see if they can block certain numbers from calling you??? I don't know why I think they can do this, but if it shows up on the caller ID, then why can't we block certain numbers from calling?
Something to think about anyway. Good luck!
