Why would my ex call me after no contact?

Anonymous
The last text I sent him was a month ago and I told him I never wanted to talk to him ever again because he broke my heart because he was ignoring me so I never tried to contact him after that and yesterday he text me "Hey" then called twice but I was busy and didn't see the missed calls or text so about 2 hours later I text him back "Hi" and tried to call him once but he didn't answer and he hasn't tried to call me back.

Why would he call or text then when I resond he doesn't answer? And why would he call after a month of no contact?
