Im pregnant and scared Can a person ever change

This is very long.

A little more to add, I’m almost 22 and have my own place with my daughter, as well as a job and savings.. I could in theory have another baby, it’s just childcare and finding a career after graduating college that would be the issue plus being single and having no support.

I appreciate all the lectures but I know I was stupid to not cut him off a long time ago. I realize that. Some supportive advice would be nice. I’m an adult who made a mistake by continuing to hold onto someone I knew wasn’t the one. I don’t need lectures or judgement. I want to keep the baby I just don’t know how.
