To make a long story short; the family member who's disruptive is my boyfriend's sister in law and we don't know what to do. His family is chinese and she's very traditional and so she's going by those rules and so forth. She married his oldest brother in February 2004 and his father welcomed her into the family and everything. Unfortunately, his brother died in August 2005 and she's still living there; not paying any rent or any money whatsoever and she hardly helps out around the house and constantly gets into arguments with his mother. From day one, they didn't get along but it seems that ever since she lost her husband; it's been getting worse.
My boyfriend's father almost died in September 2005 but he recovered though his one lung is not as strong as it used to be and so he has to be very careful and is using oxygen all of the time. He doesn't need all of this stress and hearing those two go at it all of the time. His wife has always been that way so they are used to it but his daughter in law can't understand why we tolerate her and her crazy ways.
So, what I want to know is how do we get the daughter in law to leave. According to her, she married the oldest so the house is also hers and she's not leaving. My boyfriend's father tried reasoning with her but she tells him off too. She has no respect for them at all.
She takes control of almost everything even though they let her live there and let her use everything. She's not welcomed at all and she's not happy so, why live there?
If it was me, I would've left a long time ago. My boyfriend says that his father is afraid of her and what she might do. He wants to do something but he and/or his father have to be careful about how to do it because we don't want it to get really ugly.
Any advice would be greatly appreciated. Thank You! :(
