Hey Stratman
It really doesn't matter who we think is right - the main issue here (as far as this forum is concerned) is you and your well-being.
Addiction loves chaos. Recovery not so much.
I can't really see why you'd want to make this your fight.
I understand about your kid and the house - I'm not an expert on other countries law but I'm sure you could get that changed to another address...
You're an adult. If the atmosphere there is preying on you I wouldn't want my son there anyway.
Maybe it's time to move out, man?
