<human>: Give me the gist of the text in a nutshell

Okay, so I went on a date with a girl, last week whom I met through Tinder, it went well and we were texting for a while but she eventually told me that she wasn't looking for a relationship (which after getting to know her, was what I wanted) and that she wanted to tell me that sooner rather than later. No big deal, I appreciated her honesty and we went on with our lives. 

Fast Forward a couple of days, to today, and I match with a girl on tinder who goes to the same school as me. But I recognize her face and name instantly. It's the first girl's roommate. How do I know who this girl is? Girl 1 told me about how her roommate has been sleeping around with guys from tinder ever since she and her old boyfriend broke up and how it's annoying her that she's getting sexiled. 

I did a little facebook research and boom: I find girl 1 and 2 are indeed roommates. So here's my question: Even though girl 1 said that she just wants to be friends, is it wrong/weird if I try to pursue her roommate? Whether it's for something casual or something serious?
<bot>: Went on a tinder date last week, didn't work out, matched with her roommate and want to try to start something with her or maybe something casual and don't know if I'd be a dick for doing so.
