I'm confused. (It's also been a long day.)
Are you asking if expectant parents who match with a potential family and then decide to parent should remain in contact with said potential family?
If that's not what you're asking, I apologize. As I said, long day.
If that is what you are asking, I have often wondered whether or not D and I could have salvaged a friendship if I had decided to parent. The answer is probably not. Feelings are bound to be hurt. Understandable, to a point. Of course, this point right here, hurt feelings of the potential family, are often why I feel that expectant parents who match prior to birth feel obligated to place. But, that's another topic.
I'm rambling. In short, I do not think I would have kept up a relationship with a family who did not parent my child had I parented my child.
I think this can further be discussed in the manner if an expectant Mother matches with X-family and, through the months, red flags appear and she decides not to place with them but with Y-family. Should she be obligated to have a continued relationship with X-family? In my opinion, no.
My brain hurts.
