Help...pls...

So I think I’m bi....but idk if I am or not. When I scroll through musically (my page is @savage_ashlyndobre if you want to follow me😉) and I’ll be attracted to some girls. But I sort of don’t want to be bi but I sort of do at the same time. My moms side of the family will except me but my dads side won’t (my parents have been divorced since I was 4 and I’m currently 13) my great grandma doesn’t think it’s right she’s super religious, my dad most likely won’t accept me. And my gma is my world I love her sm. She doesn’t think she’s right either but she also thinks “two each is there own) she doesn’t really care at the same time. All of you bi ladies out there how did you know that your bi?💕🏳️‍🌈
