I want to say goodbye to my wife and step down as her personal (free) Chauffeur

I have been married to my wife for 10 years, we have 3 kids, it has been a battle since day one. I have a feeling she doesn't want me around anymore, but as she relies on me to drive her around and I pay for everything, she's still wants to be married.<br><br>I want to step down as her driver, but she doesn't want my money or anything else from me, only my time, helping her with errands and picking up the kids from school.<br><br>I don't know how to let her go, I'm tired of spending my free time on her and kids, we don't go on dates, don't have any hobbies together, she doesn't do anything for me, she has me wrapped around her finger. I want to let go of the marriage, she is not a partner, just an extremely dependant partner who doesn't want to let go.<br><br>Any advice on how to free myself from the role of husband driver?<br><br>**TL;DR:** I want to leave my wife and divorce her, she relies heavily on me for transportation like a chauffeur, I need advice on how to let go.
