Confused 🤷🏾‍♀️🙄

I’ve identified as straight my whole life. I’ve been in multiple relationships with men but it’s my senior year in high school and this one girl has gotten my attention. I decided to give her a chance now but now idk what I want and if I’ll see us long term. I don’t want to hurt her but I don’t ever see myself being with a woman long term. Is it that deep or do I just like what I like and I should let fate run its course?
