Flirting/Sexual Interest?

Hi Need Advice : She (24F) has a boyfriend (her Sugar Daddy) but likes me and has sexual interest. She has 2 kids and a sex worker. She has substance abuse issues and a scammer. She's also an alcoholic and likes to party in the club. The current boyfriend is not the father of the 2 kids. She's living in with her current boyfriend and not with her kids. She’s also my classmate. I am attracted to this girl. What should I do?
