Input: I know a lot of posts on this subreddit are obviously YTA or NTA, but I'm really not sure about this one so here it goes.

I started seeing this girl recently. She has been great and it has been going fine, but here roommate isn't exactly the coolest. She is super NYC fake rich white girl, a vibe that I know well as an NYC resident. I don't usually care that much as there are a lot of fake people here in NYC at my age and I have learned to deal with them.

I had hung out with my now girlfriend and her roommate before, but she \[the roommate\] was always extremely standoffish. She would never talk to me directly, usually jump at the opportunity to mock, and was just unpleasant around me. Whatever! Fuck fake people I have 10 million others to connect with.

However, me dating my now girlfriend has sparked up the instinct part of every white girl wherein they are determined to become besties with you because you are now dating their friend. My girlfriend even said she wants to "re-introduce ourselves". This REALLY rubs me the wrong way because she has been a majorly uncool person to me before and now I auto-magically gain acceptable status. (If she wanted to be cool she would have before!) I really don't want to "re-introduce" myself and been actively saying no to invites to events by my girlfriend because I really don't want to be around this person. I know this seems kinda petty, and I'm sure that she would behave more appropriately now that she knows we are going to be in closer contact, but that fucks me up even more cause I really don't want that fake-ness in my life.

AITA for not giving her a second chance, or am I justified in just blocking her out?
