He is could either be still in love with you, miss the sex, or just miss talking to you. It all depends on what kind of a boyfriend he was and who broke up with who. He's lonely. He might want you back, but by now he would have made that clear to you. He might just still want to know you still have feelings for him, then he feels better until he wants to hear it again. If he drinks, he just might be drunk dialing. He also might want to find out if your dating anyone else yet. If this makes you uncomfortable, tell him to stop calling you.
You may not call the police randomly unless it is an emergency, because they can give you a fine.

This is simple. I call it American manufacturing. No attention to detail, carelessness and sleeping on the job.
Ask an actual question and maybe someone will answer it for you.
They are friends!
