Am I in the wrong for talking to other girls while seeing someone?

To be exact im talking to roughly 8 different girls. One that I've been talking to for a while told me she's looking for something serious. I told her that I'm not ready for something like that and that I was still gonna talk to other girls. But she's been sticking around, I've taken her on dates etc, ig in the hopes that I'll change my mind. But I still talk to other girls. Sometimes I feel bad then I remember I did tell her straight up that what I was gonna do so.. am I in the wrong?
