Bff love

I’m in love with my best friend and I don’t know what to do! We get on do well but he comes to me about other girls and asks me to help him with them because he’s shy, what do I do do I tell him or do I leave it

UPDATE

I’m scared to tell him about how I feel in case I make things awkward because he is way too good for me,

A group of us went out on Friday and it was like split into couples basically and all that was left was me and him and we had a great time and I just wished it went on forever and that we were a thing
