How to deal with a controlling mother without ruining our relationship?

I’m 30 years old and went out on a date with a man that lasted from 3pm-10pm. We had a wonderful time. My mom texted me this while I was on the date

“Are u back? I can’t believe u would trust someone enough to go off with them and you don’t even know them. This is crazy”

Along with “how long will it take before you will be back”

She checks my location constantly and tries to control where I should go, who I should be with. It’s terribly exhausting and gives me anxiety while I’m out trying to just live. Usually I’d just give her what she wants and come home but I texted her this.

“I know you worry about me and want me to be safe. I appreciate that. But I’m an adult/old enough to manage my own time, and I don’t feel comfortable explaining why I’m out for a certain amount of time. If you are bothered by my choices I don’t want you to feel comfortable sharing that with me because that interrupts the peace that I’ve made with my choices and the things that I want to do. This is why I don’t share my location with you anymore because you struggle to understand this. Your behavior is loving but controlling and I do not want relationships with anyone who wants to make themselves happy by depriving me of my right to choose how to govern myself. I do my best to offer you reassurance that I’m okay and I’ve made it places but as far an expectation on what I should be doing, when and where, that’s not how an adult should operate and I’m not willing to tolerate that type of control in my life. I love you ❤️”

Her response

“You have harassed me on my dn whereabouts since I meet your ass(she’s talking about how I used to call and ask where she was at when I was a child smh) And now that a man is involved you’re with some other shit now if you think go off with someone you don’t know bc this nigga feeding bs to your ass. Is smart have at it? You will regret trusting any mf like that. And turning off your location is on you, when someone attacks your ass you’re going to wish someone had it. Your ass just called me Saturday talking about the street blocked off and all this, and wanted advise. But, when y’all get the attention from a man you turn into something else, which is good I’m

Cool with all that. I been through this shit before. So handle your life however you want. But I promise you going off with mf you never seen mad before you will see and turning your location off. Life will show you. I will save all this reckless texting when the shit hit the fan. Good luck. Enjoy your peace! And I’m good.”

I did not respond and will not respond. She is now refusing to speak to me. I love my mom. How do I handle this without ruining the relationship?

Other context that might be relevant. I am unmarried, without children, I live with her but only to help support her financially(I’m an attorney), and a virgin waiting for marriage. If I move out she won’t be able to afford her expenses since I won’t be able to help her as much but I’m seeing this as the only option. I hate how control feels. I’m tired of it. I’ve felt this my whole life and it makes me feel trapped.
