Did I BECOME aromantic? Is that possible?

Basically up until I was 16 years old I had no problem falling in love and having romantic feelings, however, one day I started having platonic romantic feelings for a straight boy at school and the impossibility of anything ever happening crushed me emotionally, like a lot. It took me over a year to get over him and after that I just couldn't feel anything romantic for anyone anymore, even if I tried. Now I'm 26 and I still don't feel anything romantic for anyone, ever. No crushes, no need for romantic connection, and I've been like this for 10 years. I met a guy in 2024 and we started dating, and we did so for 6 months, but I had to end it because as much as I loved him as a friend, I just couldn't bring myself to feel anything romantic towards him, and that was affecting our relationship, because I was always too cold emotionally (he knew from day one I had trouble with romantic feelings).

With that said, can I be considered aromantic? Or are (seemingly irreversible) emotional blocks something else?
