career direction after mat leave

I am currently on mat leave with a 3 month old bub (I also have 2 older children) and questioning my career options.
I love my job very much, I love the career I have chosen and would love to go back mid next year, however I am very nervous about returning as it is a very toxic environment and I already have anxiety and makes it so much worse. I know the workplace will not change and might even be worse by the time I return.
It is very far from home so will add at least 2 hours on my drive

back story.
my previous partner almost ruined us financially with his spending and debt, I was lucky to have this job as it pays very well and was able to refinance and keep the house after the separation. I was also so worried about money and trying to fix his stuff ups that the job became very important to me as it meant my security.

I am now with a man with a stable income and no longer have to worry about money in the way I did before.
He is also very unhappy would like to quit his job and start a business, I know he will do great and I want to return to work so he can follow his dream.
He knows how mentally damaging the workplace is and is not keen to see me return, there isn't a lot of work in my industry, I am open to other options but I'm concerned if i leave I will find it hard to get work again and I know I will be taking a pay cut, not big but maybe 10-15k or so. On the upside it would be good to be closer to home

Is it worth it to stick to what you know or take less pay and a gamble to find somewhere with a better culture and closer?

There are so many options in my head and need to decide soon, I am unable to think objectively so looking for some different points of view.

Has anyone been through something similar and what did you decide?
