How to deal with a girl who's best friends have realised that you like her?

This girl who is literally the most beautiful girl you will ever meet I met at a concert she was the moderator and I was one of the singers. The following day i saw her she came up to me and said i sang great but i was so shy i didnt proceed to have a convo. Then well very important though I had to go up to her and give my no. so that in any future events i can be considered. I saw her the following week and she looked at me and smiled as she ped by me and then in a drama production where i had a leading role she was present (she did not know i was going to be apart of it though). However when i went looking for her afterwards she had already left. I asked her friends if she will be present this week at a group but they said the next two weeks she will be. I know i should not have made it so obvious but you have to forgive me i am so in love with this girl I sent her a friend request on fb something i really should not have done until i knew her properly she didnt add me which is expected. But the next week when i see her friends should i talk to them normal or just ignore them. And when i do she the girl she knows i like her what to do and how to talk to her?
