she starts joining calls/playing games with us. Everything was completely fine until she came back and pushed me out. I never get messaged to be asked if I want to play games any more, they all want to play what she's playing. I ask if my best friend wants to play D4 and I get "no" snapped at me.

And you know what, if she finds this and uses it against me, it'll just go to show that she has it out for me, and that privacy doesn't mean shit to her.
