There's three types of relationship arguments. One, you did something wrong. Two, she did something wrong, and three, nothing is actually wrong, but she's emotional.

This is a clear cut case of nothing is wrong, but she's emotional. The important thing to keep in mind with this type of argument, is to never play "ping pong" in this situation. Which means, she's going to accuse you of something, do not return the criticism. Just take whatever she throws at you. Remain calm, like your parents responded to you when you were 6 and throwing a tantrum at home. Just let her vent.

So after she starts crying and yells all this at you. Say something like, "ok, thanks for bringing this to my attention, I'll keep an eye on it in the future. Any examples you can provide so I know what to look out for?

She'll say something else louder. Respond with, "Oh, I didn't know. Sorry about that".

Let her go. Like when you're fishing, and the fish starts fighting. Don't fight back. Just let it tire itself out. Then, calmly and slowly reel it back in. Just keep saying sorry. At some point, she's going to be blaming you for insane bullshit. So when you reply with "Sorry", she's going to realize she's being crazy. There is now way this will fix your problem. She is not looking for you to apologize, or change your ways. She needs to know you're willing to take her side, against you, and reality itself. She wants to feel supported.

You don't want that. You want her to feel safe venting, and safe expressing herself, but you do not want to support outbursts, because that will increase the prevalence of outbursts.

So treating her like a 6 year old having a tantrum, is exactly what the doctor ordered. You love her, and you're not out to hurt her feelings. It's clear you're staying calm in the face of her storm, and you're not going to freak out too. It doesn't really matter what her complaints are, or how upset she is, or how you respond. It's going to be two or three days til she gets over it. In that time, don't be around. Find shit to do, and give her space. Days later, when she wants to talk about it, just say, oh, no worries, babe, sorry about all that. Lets get icecream. Done. Problem solved. You didn't get in an argument, and you got 2-3 days to yourself. Easy peasy.
