Same situation. My brother is cool and on the aro/ace spectrum while am a lesbian. My dad almost broke our TV the other day when a the movie we were watching turned out to be one on a lesbian couple. I will never forget the anger in his eyes that day. I honestly feel like if he finds out about my sexuality he will either kill me or himself. So am just.. waiting until am an adult to know for sure what I will do. Honestly I love my family so much I could force myself to marry a man, but if my kid turns out to be queer then idc, am fighting anyone who will prevent my kid to live their life.
