Why does my ex want to talk to me?

[Trevor]

My girlfriend broke up with me a couple of weeks ago, we talked and had arguments and so forth. Last night I heard she was saying shit about me behind my back, so I sent her a message today confronting her about it. She never denied not saying anything, and for once she said I had a right to be angry. She told me that she didn't want to say anything over a message so she invited me to walk with her tomorrow? She is the one who broke up with me, what does she want? Do you think I should talk to her? Of course I want her back because I feel like I was falling in love with her but she has been a real bitch to me so I am uncertain of what to do
