Wow! It must have been so difficult, I know thinking 'if he shows up I'll call the police' and actually doing it are very different. Well done for being so strong and not allowing him to manipulate you any longer.
I hope he gets the help he needs, but he has to recognise that he needs it I guess. Hope you get a good night's sleep and feel GOOD in the morning, because you deserve to, you did the best thing you could tonight.
