Am I being too judgmental ?

My mother is 51 and has been legally married 4 times. Her longest lasting relationship was from 2003 to 2014 to a man who abused her physically, mentally and emotionally- thankfully she didnt marry him.

In 2016 she met her now boyfriend,who has been legally married 3 times.

My mother has decided she wants to get married tonight right at 12am to bring in the New Year. Everyone else thinks they are good together and thinks this is a good idea. I however think she’s being stupid and here’s why.

They fight and argue at every other day (he’s called her a bitch twice that I’ve witnessed)

When my mother is talking about her day and how tired she is he tells her she has no reason to be tired. That she stands in one spot all day and cooks (she’s a cook for a local restaurant and works from 3pm to 9pm but years ago both of her legs were crushed from her toes to hers hips so standing for long periods hurts her)

He thinks that housework is woman’s work and he shouldn’t have to help keep the house clean

He always turns situations around and tries to make her out to be the bad guy

My mother brings home the same amount of money as him but he treats her like she doesnt contribute anything even though she pays half the bills (some of it is HIS credit card debt)

Just the other day she told me that he’s changed a lot since they first got together. And that he never hugs her, or kisses her, or asks her how her day was. She has to be the one to hug him, or kiss him, and ask about her day.

I also don’t think I’ve ever heard him tell my mom thank you for waking up at 4am to make his lunch, making his dinner or doing his laundry.

So both my husband and I think she’s being stupid. I told my sister I thought it was stupid (didn’t say way except for the fact they’ve both been married so many times) and she said,” yeah well they are good for each other.”

I responded with,” they can be good for each other without getting married.”

I’m not going to say anything to my mother because she’s grown, she knows how he treats her isn’t right, and I don’t want to cause a strain on our relationship.

But am I being too judgmental for thinking she’s stupid??

(Since the beginning of October we (myself,my husband and our 2 kids) have been staying with them. The reason for that isn’t important, but we are moving out later this week. But that’s how I know how he treats her and everything else)
