Am I a bad person?

My boyfriend Jake is not nice but for some reason I could not leave him. He controlled me. Hit me and just was mean all of the time. Cheats too.

I don’t know why I couldn’t leave

I started a new job and I met carter. He told me he wanted me as his girlfriend,wife and mother to his future children. He was so nice to me. I was going to leave Jake for carter. But Jake promised he had changed.

Stupidly I believed him and let him go.

Two years later I saw carter and I kissed him and we had sex. Yes at the time I was still with jake.

Does this make me a bad person
