What are some red flags i should look for? I came home from school and met this light skinned chick through a mutual friend. She's 6'0

and proportionate (not thick necessarily)
But she's still a virgin, likes using social media, and is was involved w/some nikka down at her school who's known to beat on women, etc

. To top it off, about 5 of us were chillin at her house last night drinking, and she starts bickering with her moms over some stupid shii

She's only 20 but damn....She has the prototype body, but some of her actions are suspect.
