Bisexual??

So i’m 13 and for the past 2 years i’ve been having thoughts about my sexuality. i recently went on a date with this girl who was absolutely gorgeous but i got stood up and ghosted. i haven’t told anyone in my family and only one of my friends know. i moved schools and i’ve realised that my new friend group doesn’t support the LGBTQ+ community and i know that if i come out to them they wont accept me, i don’t want to leave that friend group because other than that, they’re amazing people. i don’t know if i should come out to my family and if i decide to, how?!
