advive please 😢

im 20 and i lost my virginity to one of my best friends over the summer with the arrangement being just a hook up with no feelings. i dont have feelings for him at all but i feel so bad inside because he doesnt talk to me anymore. i want us to go back to being good friends but i feel so.used and disgusted with myself that i shared the most intimate part of me with him. i valued our friendship but i guess he just wanted to 'hit it and quit it'. i do want to talk to him about it but i dont know what to say because there are no feelings involved but i feel so betrayed and used. what should i tell him if we do have a conversation? should i end the friendship?
