Very sad Carlos, you will face many situations like that. I understand you don't want to mix your personal life with your professional life, but maybe people would be very understanding if they knew. On the other hand, you may not want the stigma and the comments that can come with them knowing.
Reading your sadness cuts through all of us who believe parental child abduction is one of the cruelest things someone can do to a parent. They say losing your child to death is the worst thing that can happen in life to anyone, but having your child taken away from you is no piece of cake either. You have made many friends in this forum who can listen to you in the bad moments.
