For the people who almost got an abortion and didn’t…

Or the people who got an abortion and regret it, why? I recently found out I’m pregnant, I messed up and my boyfriend and I were not smart about it, I decided that I want to step up and raise the baby even though we both work, and I am in school, he on the other hand thinks that abortion is best just because he wants us to “get to do everything we talked about in life” before we bring a kid into it. I haven’t stopped crying and am just sad so opinions please
