Do you feel embarrassed?. Dont blame you.
Several events happened in my youth that I still recall on occasions and feel the same embarrassment as I did then.
I asked a family friend if I could date his daughter. She was 17 me 27. He said no, that she was too young. Two years later she married a 30yo guy, she was 19. go figure.
And a girl that lived across the road from us. She was 21, me 16. I asked her out. She rejected me. Everytime I showed my face to the street I felt pain.
So, you feel love and attraction for this person and everyone has found out. Sometimes it is better to get these things out in the open and sometimes not. I dont think it was wise to mention it at all but now that you have - put it down to experience and accept that most people do these things and have regret.
Dont be too hard on yourself. after all you are only being human.
