My (18F) boyfriend (19M) wants me to look after his baby.

I have been with my boyfriend for a few months now and I recently found out that he has a baby on the way. When i first found out my first thought was he's not my baby so I said I would not be involved. However i am going to still be with him as I don't want to punish him for having a baby. <br><br>He said that he wants me to look after the baby. However I'm still in school and have no desire to look after a baby. I told him that I did not want to look after the baby but he has yet to accept this. How would I approach this situation? I feel as though he is emotionally black mailing me.
