<human>: Can you provide a brief overview of the text?

My ex-girlfriend and I broke up a couple months ago. I made sure to engage in no-contact to do my best to move on with my life. I tend to struggle with break-ups, so I wanted to do what I could to make this one as healthy and as much of a learning experience for me as possible

Well tonight... she messaged me. I folded and responded to her. She made small talk, told me she missed me. Suggested that we talk a walk in the park sometime soon. Then, after a bit, she makes sure to let me know that she is seeing someone new now. 

This really tore me up. I know I'm biased and obviously hurt, but I feel like she did this just to mess with me. Why else would you go through those steps like that? Now I'm very hurt and I'm frustrated. My exes always seem to move on so fast while I'm always left alone and hurt. I don't know. I guess I just need someone to tell me it will be okay.
<bot>: Ex-girlfriend and I broke up. I was moving on well and good. She pops back into my life to make sure I know that she is seeing someone else and I am still alone.
