How likely is it that I will get full/most custody?

The father lives an hour away from me. He goes to university ten minutes away, and is living in a dorm on campus next year when the baby is here. I am breastfeeding as much as humanly possible. I want as much, to full, custody as I can get. He has no emotions towards the child and expects his parents to do everything (he is going to be 20, pathetic). I do not trust him with my child. He refuses to work with me for the good of the baby.
