Advice Please

I am getting to know a guy and he is amazing. I want to be honest and open with him. I was engaged twice in my past. First time was my first relationship it was rushed and he had mental health issues, I stayed with him until he was safe, even tho he would show me pictures of a woman he wanted. He would send it to me. Yell at me and I was always on phone with hospital making sure all was good. I still stayed until he was with family okay. I was drained and I was losing myself. The second one was years later and we just didnt work out together. We thought we were good but it wasnt healthy. Since then I have not been in relationship or dated or even talked to any man for over 2 years, healing and learning. Growing and learning from my mistakes too. Then I met him. 🥹 I feel safe with him. We had recently started talking. How do i tell him, I am scared he will see me as a bad person. 31f. Thank you for your advice.
