How should I handle responding or not responding to her?

So to make a long story short I wanted to stop talking to her because she wanted to fix things and when I asked to talk it out she lied and said she’s going to sleep but instead she lied to talk to another guy and I’m just sick of it so I said I’m done and don’t want to talk anymore. After a week of no contact she texted me she misses me and I don't know how to handle go about handling it because she hurt me but I also still have feelings and don’t know what I want. Any advice or suggestions.
