Coming out?

hey guys, erica here. So the other day, i came out to my dad, little sister, and best friend. My dad was fine with it. My little sister, well, thats a different story. She refused to go near me and she wouldnt even talk to me. I felt bad bcuz i came out as my true self, and she didnt like it. My best friend was like, "about time! I could tell, considering you've already "accidentally" kissed a girl." Ok well it was an accident. I tripped and boom. Straight on the lips. Well there goes my first kiss, i thought to myself. And now i have ANOTHER problem. I'm debating whether i should tell my boyfriend. I have no idea how he'll react. No idea. My dad says i shouldn't, but i feel bad if i dont tell him, bcuz i would be keeping a huge secret from him. Plz, if you're reading this, comment below and tell me what you think i should do. Bcuz i have no earthly idea.
