I'm 18 and Bisexual even though. Hate the fact that i am. I was talking to my mum about another Bi girl when mum said she doesn't believe in bi. This isn't the first time that she's said this (and venomously might I add) and even though I'm pretty sure she knows I like girls I feel as though if I ever met another girl (there was a few before my boyfriend I am currently with) I would have to hide her from my mum. This upsets me. Should I brooch the subject more or just leave it as it stands?
