I am into this guy so much. He seems so right for me and he is the one I want 2 keep me tied down in a [cont.]?

relationship.. I am getting mixed signals from him I feel like. We talk everyday and my feelings are growing for him... BUT.. I am getting feelings for his best friend. His best friend and I have been talking a lot lately and I think I am catching feelings for him. He is everything i look for in a guy. I just don't know what to do now. I wanna be guy number one so so bad but his best friend is so perfect. What do I do...? I am asking now because I don't want anything to get to serious between all of this.
