First crush

Mia

I found out I was bisexual in August (I have a preference for girls) and just recently i think I’ve gotten my first crush on a girl since I can remember (I probably had crushes on girls when I was a lot younger). I haven’t had a crush on someone (who’s not a celebrity) in 2 years after I broke up with my boyfriend. I’m sure she’s straight but I just don’t know what to do. Help???
