Mixed emotions

My boyfriend of almost four years told me that he doesn’t want a second child. I just had a baby 9 months ago. I told him once I’m done going to college we buy our first home and get our lives going the way we want I want a second baby. He keeps telling me no it’ll never happen. I tell him how I want to redo everything I never got to do with our second ( due to living with family I couldn’t breast feed or store milk in the fridge). I want my son to have a sibling/ best friend. Ugh 😭😭
