Stuck in the middle with you

I was put in the middle of a fight this evening, between Saki and her mother.
I could go on for days as to why the fight happened in the first place, the underlying issues, the real fight they were having, what her mom is really angry about, but then this entry would single-handedly outlength all others combined.

The bottom line is, they had a fight, and I was standing there the whole time.

What the hell am I supposed to do in that situation? I can't step in.

What makes it worse, is that then, her mother looked at me, as I admittedly glared at her with straight up loathing, and asked me if I understood what they were talking about. Which I did, entirely, more so than her. She then told me I should think more about Saki's condition, having just gotten out of the hospital. I won't get into the details, but it was a ridiculous thing to say to me.

The thing that makes it worse, is that I can't say anything. I can't do anything. I can't fight with her, she's my girlfriend's mom. We're not married, and it's not my fight. But as if it weren't bad enough that she fought in front of me in the first place, then she had to not only drag me in, but ask an incredibly condescending question, and then, to top it all off, talk to me like it's my fault. Knowing the whole time, there's not a word I can say back. Nothing. Zip. Zero. Zilch.

We wound up going to a manga cafe to eat our dinner that we had bought, and we laughed about how we felt like homeless people seeking shelter from the winter in a place like that. We dicked around on the internet for a while, and I think being there together really helped Saki.

But I worry, that she has these feelings that she's being forced to bottle up because she lives with her. And that scares me, because I don't want the same thing to happen to her as happened with her mom. I don't want her to be a slave to feelings she was never allowed to talk about. So, my job is to be there to help her let those things out, before they become a toxic poison inside her. I hope I can do that for her. That's my only goal.
