Cloning and monitoring ! Help!

I am a single mom with some limited but good know-how of how an Аndroid phone works. Мy device is most certainly compromised, and I do not really have the budget to hire a cybersecurity expert or to purchase another one thousand dollar phone.... Verizon Wireless will not help. I've also been unable to reach anyone at Google developers. However, I am somehow married to an unknown Linux machine that used to come up as a Google Coral device. I also have active audio mirroring and I.MS logging occurring as well. I have done some digging and found that when I speak into my microphone, this person is doing something called silent listening. Furthermore, I see a lot of Samsung Knox activity. However, when I called Samsung Knox, they do not show any of my devices as enrolled. Furthermore, every single account in my life has had full account. Take Uber or my social media accounts. Write down to my bank accounts. Every single one of my Google accounts seems to be compromised no matter how many times I change my password or two-factor authentication. Yes, I have tried a factory reset. I have not tried to flash my device or game root access. I don't believe I have the necessary experience.
