My girlfriend has a violent side when she is in a bad mood. Tonight she got into a fight with her mother to the point where they weren't even looking at her. I was on facetime, and she told me to mute myself a couple times but I only heard the last time, to which she yelled and cursed at me.

She hung up and that's when the fight with her mother reached the peak. After about an hour, she called back and explained what the fight was about. I empathized and asked for an apology for lashing out and me. She proceeded to say that I should know how she acts and that she doesn't need to apologize for anything.

We stayed on facetime working on some stuff by ourselves. She said she was going to go out with friends, stay the night with one of them (female) and that she'll text me tomorrow, or the day after. I asked why she was going out, and she said to get away from me. I said okay and we hung up. I texted her one more time just clarifying what problem I have and she said "You're too sensitive. You're too laid back."

This seems hypocritical to me and to not be laid back, I want to discuss this further tonight and stand up for myself, but she is still in a violent mood.

Finally here is my question. Is there any advice on how to be less sensitive to the things she says when she's mad, and how to not let things go too easily?" Kind of a contradiction, I know.

Thanks in advance. Any advice is appreciated.

tl;dr: My girlfriend thinks she is always in the right and that I'm too sensitive/too laid back in our relationship. Is there any advice on how to be less sensitive to the things she says when she's mad, and how to not let things go too easily?
