I really need help/advice on this situation I’m going through rn.

Basically I like my guy friend, we’re really close friends and we’ve been friends for like 3 ish years. We will call my guy friend Car because idk I don’t want use his real name anyways, car and I have been close friends for sometime and we talk about literally everything. We’re so close we’ve both talked to each other about family/personal things most people would be uncomfortable talking about and we talk about literally everything even guys Ive like/find attractive and sex... when I mean everything I mean everything. He is an amazing friend to me and he means the world. Car and I have a weird relationship because although we’re just friends I’ve always felt something between us but I always thought it would be weird because we are best friends and stuff, but lately I’ve realized that I actually like him more than a friend and my feelings about him have been bothering me so much... I just want him idk what to do or how to control these feelings..

I don’t know if he found out through my behavior or through someone but I feel like he knows I like him, I might be paranoid but what makes me think that is the way he’s been acting lately.. we use to hangout so much and leave class to see each other but things haven’t been like that for the past week and a half and ironically this past week and a half I realized I had feelings for him in a non friend way. I feel like I have ruined our friendship already

Because now neither can I have him as my best friend but I can’t have him any other way period. He’s been so distant and it hurts, like at school and even over text. I don’t know what’s going on but I just miss him.

What’s the best way for me to approach this situation?

Should I give him space and ghost on him for like a week?

This situation seems just so weird because he seemed so into me when we were Normal like i felt something between us and now I just feel crazy and regretful.
