My phone's a sex line

I've had sex with three different people, the first two I had been dating for ages, I genuinely "loved" them (I was young it was more an infactuation), the thid was a close friend after a dodgy break up, my ex somehow found out and got my new number posting everywhere that it's a sex line, I've changed my number since but he keeps doing it, I don't know how he gets my number.
It's very scary to get calls like that what should I do? I have contacted the police but until they have prof it was him they won't do anything, I've aalready changed my number.

Tell the police!!!

make sure when you call for a new number tell them you want it unlisted...call them back and tell them that you still can...then only give it out to trusted friends and family, if he still finds it out either one of thoose people you told are telling him or he's borring there phone or contact book and getting it himself the sneaky way! make sure when you tell them your number tell them not to tell anybody else because your only giving it to thoose you want to have it...hope I helped.

Set up the voice mail to come on and say "Thank you for calling ___ whatever free sex hotline you want...

Then continue and say... "Our new number is___ and give his number...

wow looks like your ex is extremely jealous. What a stupid jerk. I would suggest getting caller ID and ignore the calls that you get from unknown numbers. Slowly this will die down and don't let you ex know at all that this bothers you...thats what he wants. Just let it pass and hopefully you can get proof that he did this. I wouldn't suggest doing the same to him if I were you...why stoop down to his level? He's not worth it girl.
