What if we have feelings for each other?

ok you see I have one of the greatest guys in the world and I have a real good friend. I've been bi since like as far back as I can remember and ever since I told my friends I was bi my best friend came and told me she was too! since then weve been becomin closer friends and today she asked me how id react if she told me that she liked me, adn I told her the truth which is basically that I've liked her for a long time just didnt have the courage to say it. so now I've got my boyfriend whos sooo sweet to me, adn everyone likes him and he picked me, but then theres my "girlfriend" who I also like but I dont know if I can live without either one adn I just dont know which one I should like the most. my boyfriend doesnt know that we have these feelings for each other and I really dont want to tell him cauz it would hurt his feelin way bad because he is openin himself up to me, which is a first for hime to do in like 2 years ever since him chic of 3 years broke his heart he never went out with anyone until me. what shoould I do?

I know this might sound wrong but maybe yu shud just keep it to yurself...
