He is a legal stranger, with no more legal rights than a bioparent after adoption. While an adoptive parent is free to have an open adoption with the bioparent, they can cut off contact if the legal parent's right to parent is not being respected.
I'd suggest you put your foot down and tell the donor to back off and you will parent your own think, thank you.
I agree. HOWEVER, since others may actually search for information and find this thread (although I haven't seen that much evidence that people actually use the search engine on this site
), I'll add the following:
The above is what happens when you try to play games outside the system. Then compound it by letting the father be in the child's life at the same time you don't want him to be any part of the child's life.
You don't get to have it both ways. If you want to have a baby without a father being involved, then get an anonymous sperm donation through a licensed center. If you want someone you know to be the father, then plan on them really being the father, not just a donor. And if you choose to not let the father be a legal part of the child's life, then don't complain about not getting child support. And if you don't want the father to be involved, don't blame him for the child's misbehavior. BE RESPONSIBLE FOR YOUR CHOICES.
