Why can't I stop contacting him?

I can't stop texting my ex boyfriend from time to time. I know he doesn't give a sh*t about me but I miss him.

I know I shouldn't contact him and want to but I can't?

Have any of you had this. I'm worried that he might change his number or bar my number?

We were together a long time but he has now moved on!
