something I am wondering about

My loving wife, a few years back, talked her aunt into opening Lane Bryant, Sears & penny's. Her Aunt bought some items for my wife with the understanding that my wife would pay the aunt back. So every month my wife would take her money. Every now and then my wife would take it to her a little late. Auntie said no problem. Then Grandpa passed away. Auntie moved to her daughters house out of state. Now my wifes cousin is comming on pretty strong saying my wife srewed auntie over. She has called and demanded money for paymnets along with late fees. I guess auntie was not making her payments on time. My wife has a pretty good relationship with auntie only when she asks to speak with auntie, Auntie is always "sleeping" according to cousin. My wife is willing to pay for what she bought only now no one has kept track of what was bought. Cousin seems to think my wife is responsible for the entire bill for all accounts. I know this not to be true as I have seen auntie in the mall buying stuff. All my wife wants to do is deal with auntie one on one. So they can work out what is really the bottom line.
I cant believe this stuff was never paid off. It has been along time of my wife paying her

I am wondering if since cousin is daughter of auntie, is she exempted from the rules a ca must follow. I have to admitt that she has called and been pretty rude and anoying. I hate to see that this has happened.

Note that just as one might say my wife has taken advantage of poor auntie, the cousin is up to something. Grandpa left over $300,000 to be split up amoung the 2aunts and 1uncle (MOTHER IN LAW GOT ONE DOLLAR). Cousin has made it clear her intentions are to buy a house so that auntie can live with her indefinately. What ever! I just don't like to see my wife bee verbally abused

anyway any thoughts on this are appreciated.
