I'm expecting my first son within a month. The mother of my child has told me she does not want me involved in the child's life. What can I do?

Me and the mother of my child do not have a great relationship. She does not speak to me throughout her pregnancy whatsoever & in fact has blocked me in reaching contact with her several times. I'm a young father and I, along with my parents, feel as if she will be consuming all the time with the child once he gets here. I have not done anything to harm the mother of my child in any form. I'm just a father who wants to be involved in my sons life. I have explicit texts where she clearly states how she does not want to talk to me till my son is born, and how she doesn't even want me involved. Please get back to me as soon as possible.
