This is more of a vent but would love to have some feedback or read similar stories

Been single for almost a year, my last relationship was really really codependent, it destroyed both of our lives and it erased almost everything I knew about myself. Ever since, I put in a lot of work to find peace in myself, and I barely recognize the person I was a year ago. I still feel codependent but I feel like I can ease myself a lot better, I can sit with my feelings a lot longer and I’m in therapy as well. I met someone, it was during a night out and we kissed, I thought it would be something casual but I kept thinking about her so I messaged and we met up again. It’s has been almost two months and we are seeing each other. She’s very peaceful and calm, which has been a challenge, I’m used to people who get obsessed with me and have a more of a chaotic energy, it has been hard for me to open up because it’s almost like I’m feeling less secure because she’s so healthy? I keep thinking that maybe I won’t be a good partner yet, I have never been in a healthy relationship so it scares me not knowing exactly what to do in one. What’s normal, what’s not. It’s almost like with previous relationships, because it was so intense and they would share their entire life in the first date, I felt like it made sense for me to stay, they usually had problems and I thought I could help, I felt needed. With her, I feel like she’s doing amazing by herself, she’s super smart and independent, and I find myself thinking that I’m not sure what I can offer. I can identify that this is my lack of self worth talking so I’m giving myself time to enjoy our time together, but it has been a real challenge
