I'm not saying y'all need to stalk a woman's social media, but the things she posts tells you exactly who she is. Especially if she's reposting TikToks or short videos about relationships and the videos be about toxic shyt like sleeping around until they're given a title in relationship
These females be telling you they're for the streets without even realizing it.
If she's a narcissist her social media will make it very clear as well.
Also if you've been dating her she might start posting subliminal messages directed at you.
My FWB is always posting on her socials that she has a hard time finding a man that's at as high a level as her, that men are intimidated by her, and she reposted a vid that said if a man is tired of a woman acting single, then he needs to put a ring on it
The whole reason I put her in the "sex only" zone is because it's clear as day that she's not relationship material.
