Seriously!?  How can you knowingly raise a child that you know is not yours while letting your own child be raised by someone else?  I don’t think this is something that you just forget about overtime.  Imagine going through life, your forty years old and one day you find out your mother and father are not your real mother and father but this other lady and her husband are, who have been keeping it a secret since they left the hospital.  Talk about confusion, this is a case that could use counseling.
