My question involves paternity law for the State of: Missouri

I am 5 months pregnant and would like some advice as I prepare for the baby to arrive. The father and I were dating only a short time when I became pregnant. He is not interested in having a relationship with me. He is adament that I'm ruining his life by having the child.

He says he will 'be on board' once we establish paternity. I told him that was fine - we would do that when they baby comes. Rather than listen to him berate me for having the child and not having an abortion, I have asked him to not contact me unless he can have a positive, adult conversation. As such, I have not spoken with him for 2+months.

I am 35, employed full time w/ benefits, make $70 - 90k/ yr (depending on bonus). He is 32, self employed, uninsured and reportedly makes $35k/ yr. I learned on our last date in November that he is a daily marijuana user, something I did not know prior.

So... poor decision on father of child, but I am well-equipped to raise my child. I am open to his being involved with the baby if he is not using drugs and chooses to be an active and involved father. However, today the pittance of child support money he would provide is not worth exposing my child to his lifestyle or negative attitude. I'm not inclined to seek support because it would open up the door for custody. I feel if I do nothing, ask for nothing he just won't be involved. However, if my life circumstance should change (ie job loss), his financial support might be needed.

What are the appropriate steps to take?

1. Should I list his name on birth certificate? Or leave it blank?
2. Can I seek financial support without granting custody?
3. Is there anything I need to do to protect the long-term interests of the child?

Thank you for any guidance or suggestions you have.
