What's going on

My ex called me earlier to talk etc I told her I was working a double she asked if I ate I said no so she brought me food and didn't take the money.. Earlier this week she said lets be friends in hopes of getting back together SN: (yesterday she said she just want to be friends then texted me and said we can't be friends I said okay because I didn't care but then she called me later on in the night to talk) I'm so confused
