So there is this girl i like, and a guy i am friends with. neither of them know that i like her, or that i am bi. And i want to tell her how i feel but he really likes her. And he trusted me with the info, but i dont want to go against him and tell her my feelings. i dont even know if she likes girls, or how she feels about bisexuality. if she ends up beimg weirded out by it and it gets out, it could mess up my bjj training. i dont want to ruin what i have with the both of them. what should i do?
