wow, this is quite the situation, there was a past post from someone explaining your rights to the child and another about this likely not being your only chance at a family. If you decide to stay with this person(Myself and many many others would question why in the world??)you have to shore up some legal rights with this child. This would be an already terrible situation gone much worse if you and the child develop an attachment to each other and you are both separated for reasons beyond your control. You seem like your trying to do the right thing here...from your perspective, which may be seriously clouded right now. If you can't get any kind of legal rights I don't see how you can take this massive risk. If you can get legal rights and your sure you want to stay and trust this person then do it and don't look back and listen to people hating for it.
