Sounds like she’s selfish. I’d leave.
After reading her excuse for not being OK with the switching of consoles, she sounds very selfish. Not going to say drop her, but that's a pretty minor thing not to budge over. Sounds to me like it's about more than the PS4 and probably about the control of space in the household, or resentment about the second bedroom (feeling like you needed a place to get away from her). When I was dating and living with a girl, this quickly became a big issue for us after we first moved in.
Sounds like you two need to have a serious conversation about these things. She may not even realize that this is what it's really about for her.
