Looking For Advice

Erica
I'm just looking for some advice, I live with my boyfriend and his brother. And for the past year his brother has been mooching off of us as he kept loosing jobs from his alcoholism and drug abuse. And this year he was kicked out of rehab and since he moved back in, he's begun to mooch off of us again for food, money, and trying to not pay us rent. But what's really bugging me right now is that the two of them barely help me out around the house to clean. His brother hasn't cleaned the bathroom he uses since he moved back in, and he doesn't bother helping us to clean the kitchen or living room. What's the best way to ask him to clean up after himself? As we have talked to him before about cleaning up after himself.
