f**k him and the bitch that birthed him, Dani. I don't know you, but it's repulsive to me that such a shit human can make your life so miserable. Try to get some real perspective on this issue and life in general. Decide what is truly important to you - think about it right now. I'm betting he can't touch any of it. Take comfort in that and give the merkin the finger next time you see him. Unlike others, I wouldn't go chasing the money to teach him a lesson that he almost definitely wont learn (assholes invariably tend to be assholes, regardless)... unless you are hard up for the cash. It's not worth the hassle of him lingering in your life.
The only other thing I could say is let it go and move on. Make him a fart in the bathtub that is your life, rather than the shit that got poured into it.
... now, in other news, I think I got a place in Surry this arvo! Property manager is running it by the owner in the morning, but if all goes smoothly I'll get the keys on Thursday! Yay me!
