Have an aunt who has only ever lived with women. I was always told it was her roommate. Everyone refers to her as a roommate. They BOUGHT THE HOUSE TOGETHER. Have dogs together. Raise the other ones kids together.
When I was like 17, and openly gay, I straight up asked my grandmother if her sister was a lesbian. She said no they're just roommates and got super specific about it. I asked my aunt a couple weeks later when I saw her and she went "Well, yeah. Do I not wear enough flannel?"
You were just a couple that didn't fuck or have romantic intentions with each other. Nothing wrong with having a really close friend like that.
But yeah ... You sure you're not just gay? /s
I'm honorary gay! I used to have a challenge coin that said so lol.
