TL:DR I’m a college kid met a girl at an after party took her to get smokes while along the way she talks about how she “almost got raped” and her mom died of cocaine overdose at a young age

I don’t understand this at all. Seems like a cool situation at first. I meet a girl at a party she wants to get cigarettes and I say OK let’s go it’s about a 10 minute walk to the store. She’s drunk and so the whole time she’s like are we there yet are we are you sure you’re taking me there. I’m constantly reassuring her whole obviously touching her. But then she comes out saying all these crazy things like oh my mom died when I was young and I almost got raped and my mom cheated on my dad. In hindsight I think she was trying to guilt trip me into not doing something with her or backing off because I’m a big black man and very imposing so while she wanted cigarettes she also didn’t want to risk anything escalation or I don’t know. Long story short I got her the cigarettes I got her back to my place so she could use the bathroom and she kept going on about how she’s hooking up with some guy and her hooking up with me is cheating and continues to go on about her previous ex-boyfriend‘s who cheated on her and how her mom cheated on her dad

My only question is why do girls spill This private ass shit to guys they just met when all the guy wants to do is get them some cigarettes??????
