I need insight on a past relationship experience!

Hey fam, I’m back with another situation— so I recently found some old messages where I told an ex friend I had “two girlfriends” but I only clearly remember one (V), the second one is a total blur—I don’t remember her name, face, or anything about her. I know I don’t cheat so I crossed that out.. Still, the whole “second girlfriend” thing is freaking me out because I genuinely have zero memory of her. I suspect it might’ve been a queer-platonic thing though but I just don’t remember enough..

Could someone give me insight or something please?
