Should I confess after 1+ year of no contact, or just move on?

Back in 11th, a girl from my class (also a student council member later on) once offered to help me during a college food fest I ignored her at the time as the work was given to me and it felt rude to let someone else do it.

Later on, I got to know more about her (after she became students council)and ended up really admiring her. She was smart, confident, and carried herself really well. We talked occasionally but were never close, and eventually drifted.

In 12th, towards the end during a science practical, I had a bit of a bad moment with her. I raised an issue about an instrument not working, and she made a comment that felt dismissive, like I wasn’t competent and didnt know how to work with the instrument.

She even tried using it herself to prove a point, but it turned out the instrument actually had a problem. Still, I felt embarrassed and angry witnessing her arrogant in that moment.

The thing is, I had brought flowers that same day because I was planning to tell her how I felt. After that incident, I got upset and threw them away. Looking back, that was probably an overreaction.

It’s been over a year now. We haven’t stayed in touch, and when I recently texted her, the conversation felt pretty dry.

I still have a strong sense of admiration for her, but I also know we don’t really have a connection anymore. She also comes from a Muslim background, so I’m mindful about not crossing any boundaries or making her uncomfortable.

Now I’m stuck between

telling her honestly just for closure

or respecting the distance and moving on

I don’t want to come across as random or make her uncomfortable if that’s the case, I’d rather back off.

What would you do in this situation?
