I have trouble accepting I might be bi?

Im a Christian and I usually like guys but it’s like been two people only in my lifetime I have really liked that are girls. But I wasn’t trying to and didn’t really realize I was acting like I liked her and she gossiped so much about me and stopped being my friend. I had a crush recently I didn’t want the same thing to happen again so I tried not looking at her like at all really or doing anything to make her uncomfortable but I think somehow she figured out I liked her too and didn’t talk to me at all only other people. Im hurt by all this I wasn’t trying to like them it just kind of happened. But they were so mean about it and now im sad.
