The fact that you are posting about this on reddit and seeking advice means that you want to take some action on it.

I am just pasting the advice a great guy gave me on my post but its just too good not to pass on.

Do it now before you have the chance to regret it.

4 things could happen.

Rejection: At least you know now as sucky as that is. And move on to find someone who actually really wants you as their girlfriend.

You get the guy: No downsides (I hope?)

You wait around, he finds some other girl to be his girlfriend: Lose your chance. He has a happy life totally without you.

You wait around, he gets with another girl but they don't work out: You're really back at square 1 and now its the same decision but with the next girl he dates.

Rejection really isn't as bad as you make it out in your head. Only he knows how he feels about you and you burying your feelings inside is not gonna change anything. Except maybe give you grey hair from all the stress lol. Anyways I hope you find the strength to confess to him. Keep us updated on your situation and all the best!

I completely understand where you're coming from but the world is pretty huge. You've put him on a pedestal right now. You're literally just 25 years old. You have your whole life ahead of you. You will meet many many new people. And this is just assuming that the guy rejects you. What if he does feel the same way about you?

This is my story by the way

I was literally in your shoes 3 or 4 months back. You should 100% confess to him. I (M) was in love with my bestfriend (F) of 4 years. I confessed to her few months ago and although it resulted in me drifting away from her I do feel like I am in a much better place. I was scared that I would not be able to live without her but the result of us not being together proved otherwise. I have been more productive than ever and I am wayyy happier than I was when I shoved all those feelings inside of me.
