I am sure they are happy and I am not putting you down for doing the right thing by your children.  I just think it is sad that the child may never know his real Mother or her family or any medical history they might share.  He may never know his Grandparents and they may never know him and that is a tragedy.  Sorry he will pay no matter what you say. Best of luck to you and thanks for being the one parent he can depend on and thanks to your girlfriend for loving him as her own.
