Hearing from the (birth) father of a relinquished child

Linda 

What about the fathers of our children? Or, as they are called today, baby daddies? When we don't marry them and they drop out of the lives of first mothers, what happens? Today we know of fathers who fight to keep the children the mothers insist on relinquishing, but those stories from an earlier era have not surfaced, though some children must have been brought into the father's family.

But for the rest of us, do we ever hear from the men who impregnated us again? Do we want to hear from them again? Were you in love with him and has that colored how you feel about him now? How would we act if they simply popped up again? Do we feel a bond with them because of the child lost to adoption? Did you marry the father after relinquishment?
