How to get out of it?

I know it's a long time away but I have this pride event in May. But my girlfriend has a neice who hates me because I took her away from her. Also my girlfriend doesn't even want me there just to say I have a girlfriend. That's the only reason why she wants me there. But I know I'm gonna be ignored the whole time and not spend any time with her because of the neice who hates me anyway and I hate her to because she does nothing but judge me without even ever talking to me. So how do I get out of this? Because my girlfriend doesn't care but she'll act like she does. I wanna advoid meeting her because she'll just be an A-hole to me and nothing will get done aboutit like always. She doesn't even care about me in that way. She just likes to say girlfriend. Neice needs a man.
