Mother-in-law and sister-in-law trouble

My sister-in-law's husband works overseas for the state department and is afghanistan for a year. She is currently living 3 and a half hours from my mother-in-law who is 78.{her mother} she has two children ages 10 and 12 that my children don't really...

get along with but tolerate. The girl has add and is weird and the boy has issues and is mean. My mother-in-law took us to the beach for my husband's 50th birthday. First of all, since the whole family is add I had to make the reservations but didn't mind since my genersous mother-in-law paid for it. She complained about the price but I told her ahead of time. She has a hearing aid and never wears it and didn't take it to the beach{how convenient} I would have helped with the beach house but my husband took a pay cut a year ago and I just bought him a used car from some money I inherited as well as help with expenses and clothes. I have had illness issues for the last 2 years and haven't worked. My husband travels all the time and I take care of my 2 children that are 10 and 13. One is very social and the other one has issues but is very smart. My sister-in-law always complains about money to everybody but her husband is getting paid twice what my husband gets paid while she lives in charlotte nc. Since her husband is in a military zone. She is also two faced. She says one thing to me and another to my mother in law. We get back from the beach and the drama started up. My mother in law helps us financially right now but I am helping too a lot. Well, I told my mother-in-law that she could have my dining room table I wasn't using since hers broke. Well, my husband took it down there a week ago. She said she had a table of my sister-in-laws and she could measure it and get back to me. Normally my sister-in-law's furniture is stored while they are stationed abroad. It is not an expensive table. All of sudden, my mother-in-law said her niece needed the table. I called the niece and she said she didn't need it. Of course, colleen[the niece} also knows the 90 percent of the furniture is antiques and nice furniture inherited from my family. I called my sister-in-law and she said that is wasn't my mother-in-laws place to say anything about the table. Then she asks how am I going to get the table to my house in va. I said I could put it in the back of my van and hold it for her until she needed it. She never called me again to tell me anything. They were caught in a lie and she didn't know what to say. They don't like me because I have inherited money over the years and I guess my father-in-law was more manipulative than I realized. He passed away with parkinson's disease in jan. 2009. My parents are dead and I am sick of the toxic,two faced drama. I do like my husband's aunt because she has 4 daughters that are cute and responsible. My 40 year old brother in law is unmarried and still living off his mother. She made him stay in a clothing business that was failing and now is helping him pay the $80,000 off. It's all insane. I don't want to have anything to do with them.however, my kids love their grandmother. Tired in charlottesville va

how is this a question I dont understand what the question is?
