Aw, I wish I could help. But I have absolutely no experience to be giving you advice.
Last year out of random, my mom asked me if I was gay after finding out my cousin was outed by my uncle. The only reason why I figured it was asked is because now three of my cousins are gay and I think she feared of another son/cousin/nephew being gay in the family? I don't know.
Neither of them want anything to do with me. I can't ask them for advice or contact/talk to them because they all cut off the family.
Just you talking to me helps
But I can't stand when families do that. It's so stupid when it happens but I guess that's how it is. What did u tell her?
