Obviously you're hurt by your mother telling your niece what you said about her friend . I would be hurt too... all you was doing was trying to help...I would let things die down ..I would back away and let your mother handle it. She choose to deal with your niece and she's in for one heck of a ride. She already been thru rehab she is going to have to hit bottom before she changes her ways there nothing you can do,,, nor your mother,,, it's all up to her..She may be dating these guys just to support her habit...When things start going bad like things missing in your mother's home then your mother will wake up and smell the coffee and realize her niece friends are indeed trash.
