I think I may be a ?

I don't have anyone to talk to this about, but I'm 19 and I just rrecently met one of my friends from grammar school. I have a bf but things aren't going so well. I feel as if I'm becoming attracted to my female friend who i just reconnected with. I am a devout Christian, Catholic specifically, and my religious beliefs kinda discourage this kind of behavior. I am so confused and i don't know what to do!
