I met my best friend last year at a new job in Spring 2015. I wasn't interested/attracted to her because at the time, I was dating someone. I broke up with that person in Summer 2015. I still wasn't interested/attracted to my new friend after that. However, we got pretty close and started hanging out outside of work/talking often due to us going to concerts (she introduced me to new music, which has changed my life).

Now.. I've always known she had a boyfriend. They've been together 8+ years. Like I said, we got pretty close due to the new hobby she introduced to me and that interest brought that hobby back to her life.

Eventually.. the more I talk to her/spend time with her.. I naturally developed feelings for her. At first, it was a crush. Everybody gets them. But eventually.. that crush became something more.

I don't want to date her because we aren't compatible. I don't want to tell her how I feel because I think it's wrong (since she's not single). Yet.. I have these feelings. 

Am I shitty person for not telling her?
