Ace Secrets, My mother thinks I’m bi and ‘not interested’ in...

My mother thinks I’m bi and ‘not interested’ in people I don’t know. No one else in my family knows I’m not straight, and if I brought home a girl (or, hell, a non-white guy) I’d probably be disowned by everyone but my mother. I have a secret crush on a girl who is sexual, taken, and lives halfway across the country. I’m demi/panromantic. Only one person knows all of these things. I feel like I’m lying to everyone else.
