<human>: So basically my ex and I dated for a little over two years. She pretty much broke up with me although I agreed things weren't working. I moved across the country and we talked a little bit and remained friends somewhat. One day she messaged me saying she heard I was coming back to visit and that it might not be a good idea. I asked why and she told me I wouldn't want to see her because she's dating someone else. I basically told her I didn't really care  and that I was visiting for pure business reasons only. After that I told her I didn't really want to be friends, wished her the best, and blocked her on all my social media websites before she could respond. A day after that I got a message on Instagram saying that she is getting around to watching a show I suggested and she wished me luck. I didn't respond and blocked her on Instagram. Ten days later after zero contact I get a message from her on my Pinterest business account saying only "I hope you're doing really good." My question is why is she still trying to contact me? Shouldn't she be taking to the new guy she is dating?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Ex is messaging me even after blocking her and not responding on multiple social networks after she told me she started dating. Why?
