relationships

so I broke up with my boyfriend the day before prom so two days ago and I can feel his regret but at the same time I don't know what to do he called me names wouldn't let me go out and we very controlling but at the same time I never told him that I felt like that until two days ago when I broke up with him i just genuinely don't know what to do because a part of me wants to give them a second chance but the other part of me doesn't want to feel the pain that I'm in right now again. any advise?
