Career change

I want to make a career change and I have for quite some time. I am constantly coming up with new ideas for new careers but they all involve an investment i.e becoming a life coach, going back to school etc
I am 100% on board with investing money to pivot and start a new career. My husband is not in agreement. And each time I present my new venture ideas and he doesn’t agree for us to spend the money, I grow more resentment. I believe our money is ours and not just his- as we both earn it and live very comfortable but I also believe I can’t just go out and spend the money without us both agreeing on it. I don’t even know where to start to get the result I want, which is a new career.
