Do I have to return the money that my wife paid on the lease each month if we are getting divorced and I signed a lease because I had better credit?

We are 14 months into the lease and we divided the monthly payments each and every month. She's not on the lease. Now, since we are getting divorced, she's asking for the money that she paid on the car. While we were together, she's not paying for the car. I'm the one paying for it. We used the car together a lot. Now she never worried about getting her driver’s license. Even though we used the car a lot together, I did used a bit more because obviously I have a driver’s license.
