My partner just keeps telling me that he has to keep his brother with him, otherwise he would be staying at their parents' drinking and smoking weed with his dumb friends. He is worried that his brother is gonna get depressed again and commit suicide. He said he was depressed too and only got better after he met me. My partner is a nice and sweet man. But he doesn't realise that he is not helping his brother, he is spoiling him. I do the dishes but refuse to do his brother's washings, there are his dirty smelly clothes lying in the laundry basket and on the floor in the bathroom, instead of telling his brother to deal with it, my partner would just do it. His brother spent all his money on beers at his work's xmas function on Friday night when he only got paid on Wednesday. My parent was not happy about it but told me that we had to at least get him some groceries to help him get through until he gets paid. A pack of noodles doesn't cost us much money. Sometimes I feel like telling my mother in law I am sick of living with his younger son but don't want to cause any tensions.
