You’ve hit the nail on the head for me 3timeslucky about not seeming “square”.
I have a old friend like this. Has been in a monogamous heterosexual relationship for the past 15 odd years but identifies as bi. Has never been in a relationship with a woman (whether she’s had flings or ONS, I have no idea). Always makes such a performance of making sure people know how different she is - she’s childfree (but weirdly bitter and whiny about ever being asked), she’ll never get married, and made a big show about being given her boyfriend’s grandmother’s ring but it’s not an engagement ring and look, I’m wearing it on my right hand. Dude, no one cares about how anti-establishment you are. You’re thirty-fucking-six. Just live your life the way you want and be happy about it
