I was with my partner for 5 years, no children and he was always pretty controlling but he would turn situations around and make me think that it was my fault so a lot of the time I didnt realise it. Over the course of our relationship i lost contact with all my friends and family.
I eventually ended it around 5 months ago and since then have had constant phonecalls and text messages, he has tried every tactic in the book to win me back - begging, shouting, suicide attempt, getting other people to call me, blackmail, threats, crying - everything. He even drove round to my flat to see if my car was there on at least one occassion that i know of. I kept in contact with him because when I mentioned cutting off contact completely, he went berserk however, I tried to limit the amount of times I responded but he would send a text and if i didnt respond within say 5 minutes, would send another, then another each one getting increasingly aggressive. He told me that if he thought I didnt love him anymore then he didnt know what he was capable of, so when he asked I said I did love him. A couple of days ago I had finally had enough and told him I wanted no more contact and we left things ok, yet a couple of hours later I received a voicemail from someone I dont know saying "answer your phone, answer it now", in an aggressive manor.
I just don't know what to do, I feel scared about what he will do next. Do you think it's a bit dramatic to contact the police and let them know what's going on?
