It's a catch 22. You may need or want financial support at some point. But that gives him rights that cannot be ignored. And if he knows it's his baby he can come after you at some point to establish paternity and visitation which is out of your control. You're better off having the door open. My husband's best friend was able to strip his sons mother of custody because she repeatedly demonstarated that she would not let him see his child. So the courts decided she didn't have the baby's best interest in mind and have the father custody. That is rare but it can happen. Try to keep it civil. Don't try to make him come around but don't be crazy if he does want to.come around. Move on with your life and focus on you and baby and the rest will come in time.
