Was this wrong?

Recently I’ve been thinking about my past. I’ve been in a relationship now for 2 years and I’m turning 20 soon, I’ve been thinking a lot about how when I was 16, I began seeing and dating a 27 year old man. I would secretly travel an hour to his house on weekends and stay the night and no one knew except a few close friends. My friends were concerned for my safety but I never was. I was impressionable and young and felt happy that an older very attractive man would want ME. however, recently I’ve been feeling sick even thinking about the whole situation. Even turning 20 I can’t even imagine being with someone who is still in high school. I can’t help but think of this man as evil now. What would a smart, well off man finished university, with a good career, want with a 16 year old who has no idea what she wants in life and in 2nd year of HIGHSCHOOL. I just want some reassurance, is what I’m feeling okay? Am I wrong for believing he is a bad person for what he did to me? Did he even do anything wrong because I did want it at the time?
