An Unhappy Marriage

I am in my mid-40s and have one son.
It has been over 10 years of marriage,
but my spouse gets angry and aggressive whenever things don't go their way.
My son is in middle school, so I am trying to endure it
until he reaches adulthood, but it is not easy.
Currently, I am the sole breadwinner, but
my wife manages all the finances entirely.
I gave my mother the annual resort vouchers allocated by my company.
We fought because I gave them to her without telling my wife.
Do I really have to get my wife's permission even to use
the accommodation vouchers provided by my company? ㅠ
My wife also manages the money I earn.
I said I was sorry and that it wouldn't happen again,
but while talking yesterday, the verbal abuse and violence
became too much to bear. I left last night,
slept in my car, and have been walking around.
It feels like a failed marriage, and I am frustrated
thinking about how to escape while constantly worrying about my child.
