WIBTA I want to leave

I want to leave but would I be abandoning them

So my parents just moved. And my little brother is having his in laws and his new baby over in an hour. Neither me or my brother live here. However, I have been visiting often because my office is nearby and my mom likes my company instead of being alone all day while my dad is working. Both of my parents are in their mid 60’s and I’m 34 female.

My parents fight. My dad recently, according to my mom, bought things that she doesn’t think we need. I don’t exactly know the details of it because I told her to speak to him about it instead of complaining to me. She frequently says things about how he is immature and selfish and mean to her. I personally have not seen him be those things to her but I am not saying they aren’t true. I just don’t want to be involved in their relationship issues.

So today was fine until my mom started to yell at my dad once he came home from work. I was here at their house all day. I overheard yelling, slamming of doors, and throwing things. All of the name calling and slamming and throwing came from my mom.

I don’t want to be here because I am feeling sick with a cold and I don’t want my little brother to get upset with me for being sick around his new baby. But mostly because I don’t want to hear my mom talk about my dad to be the way she usually does. I love my dad. I think he’s kind. I think my mom is uhhhh not very pleasant to be around is very hard to please. She is short tempered and it’s highly triggering to someone who has always wanted to meditate their issues in the past. In my adulthood I have stopped trying to get in the middle of it. But sometimes I catch myself wanting to.

If I leave….am I an asshole? I think I should just go home. But I don’t want to abandon them.

My dad is begging her to stop. My mom is hitting him and saying he embarrasses her. This is literally going on right now. I hate the feeling of not being able to make them stop. But I know there is nothing I can do.
