A question for teenage girls and older?

There are two boys I'll call them Boy A and Boy B. So Boy A likes me, but I like Boy B and Boy B is like his best friend ever. Me and Boy A has gotten to the point where we hug before going home (in my school that's a big step). I guess I kinda lead Boy A on inadvertently, we were tight friends and thought that's all we were. I really want to get close to Boy B so he will ask me out, but I don't want to hurt Boy A or make things awkward between up. How can I become closer friends with Boy B if he may think that Boy A likes me? (I know someone's feelings is going to get hurt) Thank you for all responses and support and also for reading all of this.
