My I believe my best friend is a lesbian but she refuses to admit it for some reason. It's not that I must know because I am nosy but I just don't know why she's lying to me. We even had a thing some years ago, she constantly introduces me to her new gfs, she tells me I am her best friend, she tells me about how much she likes girls, sits on lesbian apps 24/7 and when I ask her if she likes guys her response is "yes of course". I don't get it. Maybe it's because I'm straight.
