I feel guilty after making physical relations with a best friend and lost him

[Unregistered]

hi.

i cannot say that i was in a relationship. but i used to have a huge crush on a guy. eventually we became friends. gradually it lead to becoming best friends. but honestly i never saw him as my friend. i wanted to date that guy.

well that guy is a very decent, honest who believes in only true love and only 1 true love.

at the college party i got drunk and made him drink too. i almost lost my consciousness, we got to our place and because we were drunk and couldn't think of what's right and what's wrong, got intimate.

next morning we realized that it was a huge mistake and we decided to end our friendship because if we'll talk we will not be able to forget that incident. he told me that he don't want to date me because he has never seen me through the eyes of a bf . i think i lost a very good friend of mine.
what should i do?
