My brother outed me


So I’m 14 and bisexual and my brother outed me to my dad - we were chatting about pride month and pride parades and about me being bi and when my dad walked in he asked what he were talking about I said nothing because I’m not out to him and don’t want to come out yet but my brother said ‘oh yea we were talking about Harriet (that’s me) is bi’ and my dad heard but didn’t say anything and hasn’t mentioned it or anything but I don’t know what to do. My dad is biphobic and thinks you can only be gay or straight no in between. I’m only 14 so I’m financially dependent on my parents and all that and my relationship with my parents isn’t the best either. I don’t know what to do and I’m just very upset and emotional about this whole situation. Does anyone have any advice?
