Is it normal im stuck on two brothers?

I have a guy best friend who's been there for me for years. Awhile ago, in junior high, I dated his brother. He wasn't my first heartbreak but he was the first boy I really cared about that really hurt me. I was a young, naive girl. After that, his brother, my current best friend walked into my life to be one of the coolest people ever. He's gentleman, a great student. He's motivated and sweet, as well as caring. His brother is also a gentleman but a bad student, unsure of his upcoming future but sweet and caring as well when he wants to be. He also if bad at communicating how he feels. Thinking about this, you'd think the answer is clear. But I like them both. I don't want to ruin what I have with my best friend but he's better for me. I don't know if he feels the same. I know his brother really cares about me. He randomly kissed me and told me how he felt which is hard for him. But I don't want to lead him on when I can't even choose one of them. Is this normal? Does crap like this really happen? This whole situation is upsetting and frustration.
