Considering adaption

I'm 17 and 12 weeks pregnant. I want to be a mom someday but I want my child to have the best life.. I've been thinking about adaption a lot lately but I'm scared about what the babies father will do. Or what his family will do, and I know forsure I don't want my kid growing up on that side of the family. But i feel like they're thinking about themselves... I know it's his kid too but I don't think he realizes that we aren't going to be able to do this right now. Does the dad have a say in this? Like does he have to sign anything? I want nothing more but to be able to raise my baby but I know me and him both aren't fit to do that yet. And it's not right to do this to a child that you know could have a better life.. If anyone has been through this process please help me.
