Help BF wants me to have baby, I’m not ready

I’m 6 weeks along. My BF is overjoyed with excitement and won’t even hear me considering other options. It’s a dream come true for him to have a young baby mama /stay at home wife even if I️ feel too young and want to go to graduate school next year. I️ was considering not telling him before, when I️ first found out, but he found out from overseeing an email with my girlfriend.

I️ am emotionally not ready to become a mother. I’m ok with this, and want to get the abortion pill.

Has anyone ever kept their choice to themselves? I️ feel like he’s thinking solely about the excitement of fatherhood without the reality of all the responsibilities it entails- and with it belittling my personal sacrifice to bear his child before I️ am ready.
