Handling disappearing acts

Most of us have had to deal with those oh so lovely disappearing acts in our dating past. You know, that is when someone is in hot and heavy pursuit for you for a smooth month, then suddenly stops calling. They get ghost and disappear leaving you bewildered.

Sometimes these ghosts come back to haunt you later, though. What happens then? Do you let them come back into your life if they had a legitimate reason they left?

How would you react if someone came back after pulling a disappearing act on you?
