Hi Joanna

I'll be as kind as I can here, because I really do feel for you.  The reason this guy is still in your life/harrassing you/bothering you is because you're still giving him the time of day.  Sorry  You need to want it to end.  Until then, it never will.

Writing to him just gives him more of your time than he deserves.  Turning up at his flat just gives him more of your time than he deserves.  You're possibly sending out mixed messages to him - whilst you're saying on the one hand you want him to leave you alone, on the other hand you're wanting him to be who you want him to be (IMHO).  He'll never change.  He lies and manipulates and thinks nothing of doing this.  As Anika said, you can't reason with a person like that - you can try until you're blue in the face, but he will never, ever change.

Ana gives great advice re: changing your website, photos, phone number - and address, if needs be.  Make it impossible for him to contact you.

Put him out of your mind and just pity the next poor woman he does it to (because you won't be the first, nor the last).  He is simply not worth your time and energy 

he might have paid you 1k a time at 3 time a week but look how much you have lost in earnings in the meantime and the stress and the headache and the heartache 

do what the others say  - if he bothers you then  get a restraining order  on him ( his wife will  probably end up knowing about it ) but  tough shit  he has been an utter asshole   

your probably not the only one he has done this to and wont be the last, so just kick him to the kerb  and dont anwser his phone calls texts emails ect 
your allowing him to carry on with this drama by anwsering his calls ect

and the bit about the dead wife  well thats just plain f...... sick   and nasty and i would have dropped him right there and then 3k a week or not
just imagine what he would say about you if his wife found out  - probably that your some crazy escort stalking him  and he felt sorry for you  blah blah

if you can i would say bugger off on holiday for a few weeks  and dont take your phones delete his email accounts 
he will get bored  - they always do   
     

This sounds like a situation an escort friend of mine got into about 10 years ago. It could be the same person.
