I'm stuck

My boyfriend and I of 4 years broke up and I found out that I am pregnant. I currently in one the top schools that are hard to get in. I want to keep it but at the same time I am not ready financially and mentally. I don't want to drop out of university and I want to give my child a better life than what I experienced. My ex wants me to get an abortion because he's not ready and he doesn't have a job since covid. I am about 4/5 weeks.
