A friend of mine broke up with her ex boyfriend for 3years now but he has refused to move on. He flashes her often but

never calls. If she calls him, he keeps reminding her that he loves her but he will never call her.

she actually moved on without him in the picture, now she wants to settle down with someone else and he shows up

again reminding her that he loves her and wants to marry her. 

Is this guy monitoring her or was sent to make her unhappy? Is he possesed and a devil that he keeps appearing when

she wants to take a critical decision

Please advice this lady
