Boyfriend's female best friend invited me to a girls night

Would you go?

My boyfriend and I have been together for about a year. His closest friend from high school is a woman. I've only met her a few times because she works a lot and they usually just text it talk on the phone. I try to be cool with it. Last guy I dated with a female best friend cheated on me with her. They became friends because in high school my boyfriend was raped by his friends dad and all his friends turned against him. She became his friend because she was raped at a party and everyone called her a slut while they called my boyfriend a faggot. So she became his friend and they got through high school together. I understand why they became friends and from what I know it's never turned romantic. I just don't really know her. She messaged me asking if I would like to come out on a girls night with her two other friend. I don't know why I got snarky. Her and my boyfriend had already been to a concert together recently so I asked why she didn't ask him. She said it is a girl's thing. Should I go. I mean not like she's going anywhere so I'm thinking I should try to get to know her and possibly be her friend.
