Need Help analysing my mother's behaviour

My mother is often fighting with my father about the stupidest things.
*Often she blames him for not providing to our home while he is the only one providing to my home. She rarely buy groceries but claim that she is the only responsible person in the family
* She start a fight everyday complaining that our neighbors and relatives from my fathers side are sayings thing behind her back and conspiring with my father against her, while I can see that its pure baloney.
* Once she starts a quarrel she keeps on talking about the above-mentioned things for hours even though nobody is listening, she keeps doing this until someone gets angry and talks back.
* She starts fight with my father when a relative/neighbor sees her and not smile at her. She says its my fathers fault that he said bad things about her to them.
* During the fights she keeps on exerting that she does not need anybody's help to live, that she has her money from her father to live her life own her own, she is not talking about being an independent women, she is saying that she does not need anyone's cooperation in life. She rejects the fact that man is social animal.
*She believes that my father, his relatives and our neighbors all the want the money she inherited.
*She sometimes confront people about this and they are like, "What the hell is wrong with this woman?"
*This morning she argued that an uncle of mine deliberately put a dead cat in our garage.
*She acts like everything is about her. And when anything goes wrong, its because my father conspired against it.
*She used to buy eggs from our neighbor and recently she told my mother that there not enough eggs, now my mothers says that my father told her to sell eggs to my mother.
*When any relative comes to our house, she starts talking about all these thing until they become uneasy and leave. Nobody comes to visit us anymore.
* Once father and mother went for a couples therapy , after hearing everything he said something she didn't like, after that she said he is not qualified and refused to see another expert.
* She is extremely agitated when some one points out her fault. She says she is not responsible for it as she is very hardworking.
* once she forgot to flush the toilet, when pointed it out, she burst out saying things like she is working hard for the family so she can't be responsible.
* When pointed out that she didn't close the refrigerator door she exclaimed that she bought it so she'll do whatever she likes with it.
*She had a uterine surgery 5 years ago even though now she is fit, she makes it excuse for being lazy.
