My mom is 40 & recently (2 months ago) got out of a 16 year marriage. She is dating a 20 YO boy & has moved him in the house with her 16 YO and 21 YO daughters. He doesn't work, isn't looking for a job. He smokes weed, drinks liquor and lean (mixture of cough syrup and pain pills) parties and has even brought 2 dogs into her apartment. My husband, sisters and I have all expressed how he isn't any good for her & she told us to stay the f out her business. My mother works very hard, he spends all her money and my 21 YO sisters money. He drives my moms car out of town and doesn't even have a license. My mother has gotten to the point where she doesn't want anything to do with us and she's choosing him over us. This isn't even half of what's going on. I don't want to stop expressing myself until he's out her house. I don't know what to do? Help!
