help 😓

This is something I really don't want to post because I know it'll make me seem stupid 😩 but I need advice from badly!! My boyfriend and I have been together for a year and a half now, and he wants a baby I don't. I'm still in college and pursuing a career in nursing. My boyfriend isn't in college, he just works. Anyway he wants a baby and told me that if I don't have one by him in another year he'll just leave me all together. I won't be ready in a year neither because once again, I'll still be in school. I won't finish and get my bachelors until 3 more years. What should I do?? I really do love my boyfriend, he's my first everything. Broke my virginity, my first boyfriend, etc. so I'm lost 😓 what would you do?!??
