If you indirectly found out that a friend with whom you have gone through a lot with has feelings for you, would you avoid her/him?

I posed this question in the person’s perspective because I would like to understand.
We used to be so close, our conversations go on and on. We spent one and a half semesters as college freshmen having each other’s back, joining organizations, planning classes together, dissecting our course and sharing our burdens. I knew from the start that I would see him as one of the most valuable friends I have had the privilege to meet.
But it was more than that for me. I do have strong feelings for him, but I was keen on not letting them show. I confided only a few friends about this but I never let him know. See, although I have feelings for him, I am not asking that he feel the same way nor am I expecting a relationship. I was…am very happy of the friendship that we had…that we still have, I pray.
Everything changed so suddenly. One day we were normal, the next we weren’t. Without any explanation or confrontation, he just stopped talking to me like he used to. And this is excruciating for me because I see him everyday. And we are part of a close-knit organization. We work together, we are of the same major, same department, same circle of friends.
Apparently, he found out that I had those feelings for him. I don’t know how, but he did.
I never pegged him as someone who would do that to a friend. And now I am striving for everything to go back to being easy. I am hurting. Not because we aren’t together. Honestly, I can live with that, and I accept the fact that he likes my friend (Yes, and if you would guess, she’s also part of that organization I was talking about earlier). I am all for that. I am hurting because I am losing a dear friend with whom I have confided personal things to, who I trust, who I miss so much, who I love
I need to understand him. I need to fix this. I need your help. Please.
