illu_66: THen what's the alternative?
Lie to the kid and have her/him get this false image in their head, only to have it dashed when/if they ever DO meet him.
You HAVE to tell the truth, or else you're the baddie later on in life.
I agree with you, when my daughter was 7yrs my step son died in a car accident they were pretty close, while i was supporting my husband and trying to sort things out my children stayed with my sister, so we didn't tell her what had happened, partly because i didn't know how to.
When she became older she asked why i didn't tell her and was angry about it, we talked it thro and she understood i was trying to protect her, but you can't do that forever and i was wrong but at the time thought i was doing the right thing.
Different scenario i know, but same principle its better to be honest, just think carefully about how you do it.
