tell me what is so wrong about this

I'm 23 years old, I'm currently pregnant. The father and I were not together when I got pregnant. My family has never met him. My family is very traditional and conservative so this was a huge shock to them. Through the months I've had so many difficult convos with my family. My dad basically told me I'm ruining mine and my sons life by allowing his dad to be around. My mom has given me ultimatums like "if you get the dad out of the picture you can move home" they pushed and pushed and pushed for adoption. Took months for me to shut that one down. I'm being induced in less then two weeks and I want my baby's father in the room and my parents are acting like it's the end of world. They keep saying it's incredibly inappropriate and way to intimate of a thing for us to share if we aren't together. My mom started lecturing me tonight saying "you have no clue" and I just told her "of course I'm not as educated as you are on raising a kid because this is my first, so you can't expect me to have all the right answers before I even do it." Then she kept saying you need to cut he crap. Finally injust said "im not having this conversation because there is no right answer to you unless I do exactly what you want me to." I walked away and she followed me saying "your dad and I have far more wisdom then you" and I said "ok but that doesn't mean I have to make all the same choices you do" and she stormed off to her room. I feel like I'm not being unreasonable here....?!?!
