In December last year I had a brief (3 weeks) fling with a man who I have known through friends for several years. I finished it when he lost the plot one night and shouted at me in front of my dd, for no reason, and then refused to leave my house when requested. I ended up physically throwing him out and locking the door.
I didn't hear from him for a month after that, but then he got it into his head that I was seeing someone else and started to phone up a lot. As in 40+ times a day. He sent dozens of abusive texts and emails, calling me a slag/whore/bitch/slut etc, telling me he was going to kill himself if I didn't talk to him, that he was going to come to my house if I didn't answer the phone, that the reason things had gone wrong was because he had cast a spell to get the love of a woman and it had backfired (WTF???) and so on. He threatened the person he suspected me of seeing, and tried getting all our mutual friends to talk me round. He sent cards to me, declaring undying love in a decidedly creepy way.
He also stole a phone that had belonged to someone who recently died (the partner of a mutual friend) and sent me abusive messages from it, which understandably freaked me out.
Apparently I have "done a very bad thing to him", "messed with his head", and if I "had got back together with him none of this would have happened".
This went on for six weeks, and ended when I changed my phone number two months ago. I made a statement to the police about it, but did not want to press charges at the time. The police copied down messages he had sent, and I have kept all the emails and cards.
I have now heard from friends who know him that he has since done the same thing to two other women, and threatened the brother of one of them with a knife - apparently neither woman or the brother want police involvement. Friends are telling me that his general behaviour at the moment is starting to cause concern to his social circle, and have said they will back me up should I wish to press charges, and provide evidence, including their phone bills that he ran up phoning me.
So... should I go back to the police and say I want to take it further? When I made the statement I was told there was enough there to have hime charged with harassment. I just don't know if its worth it, seeing as he has stopped bothering me - but then I think he is getting worse and worry that the next woman may not get off as lightly as I did.
