I don't know what to make of this conversation...

A bunch of my family members and I went to breakfast, for father's day. My grandma asked my cousins about their boyfriends. Then, she looked at me and said, "Do you have a boyfriend?" I said no, but in my head I was like, "I don't like guys anyways." I think she knows about me liking girls but won't accept it. I don't know though.
