Sharing Our Innermost Thoughts

Hello
When I was 16 years old. I was in a relationship with my schoolmate. We were actually good. Sometimes he feels so possessive of me. I broke up with him because it was a bit toxic. A few years later, I met him, We talked maturely and had a good conversation. Later he expressed my feelings for me again. So since Then I again started to have some feelings again. Right now, I am happy even If I am single I don’t want to get into any relationship . But he tried to be more mature enough than before. But I am so confused to get into a relationship with him again.
