Firstly may I say. WELL bloody DONE for being out and about so much yesterday that he could see you I'm 3 different places (Shame mr stalker didn't see you at the solicitors office)
Secondly I would advise you weren't around when he came to pick the rest of his stuff up.
Thirdly. If you HAVE to be there and have to talk to him can I suggest you have a pre prepared statement to fall back on. I quite like the 1 below:
"Look you lying, cheating, manipulative, freeloading, sponging, money grabbing arsebadger! I would like nothing more than to end this here and now and never have to see your pitiful excuse for a face again, but if you insist on persuing what is rightfully mine and try to claim a penny out of MY house I will fight for all that you owe me from OUR business like the van I paid for, the books I kept, the plans I drew, the sales leads i brought in and when that's done i will go after the Merc, that i have a record of making most of the payments on.
Not to mention the 4 years i kept you, the holidays i paid for, the materials i bought for the house, the legal fees and stamp duty i paid.
If you really try to get a single red cent out of me i will hunt you down and take you for everything you have now, or are likely to have in the future.
Your girlfriend is welcome to my dregs. Now fuck off to the far side of fuck and when you get there fuck off some more"
(Only is not one to be fucked off)
