My family is religiously committed family, Alhamdulillah. But there is a major problem which is going through. My mother is very friendly with us and she used to tell us all her secrets. She tells us that she loves my uncle more than my father. Even though my uncle and his family lives in another country, he comes to this country every month for business purposes and stays in our house. My mother never talks to him directly as my father doesn't like talking with non-mahram. but she sends mail , messages and even chat with him . She tells us that he loves her back. I am not quite sure whether my uncle loves her back or not. But he responds to her chats, mails and messages. My father knows that my mother loves his brother, he never says it openly but shows that he knows about it indirectly. My father even sometimes asks me whether my mother has any other email id apart from the one he knows and asks me the password of my mother's mail id. But my mother has warned me not to tell such things. My father's temper will rise when my uncle is at home and he will be angry with all of us. I have openly told my mother that such things are haram but she says that as far as she don't talk to him directly its all fine. She asks me and my sisters to translate the love quotes for her and we used to do that as she is our mother. she also ask our assistance to chat with my uncle.
Because of all this, my love towards my mother is decreasing day by day. I sometimes won't feel like listening to my mother even though my heart wants to obey her. Once, I told my mother that I want my parents to love each other and not any one else, I was crying as I could no more withstand this situation and there was an argument between me and my mother. My sister advised me not to express my views on this matter openly to my mother as it will hurt her feelings. She told me that, My mother had undergone alot of torture from my father and from his relatives (especially from the same uncle's wife). She loved my father so much but he didn't give her the same back, and even now, sometimes my father says some harsh words to my mother. she is very sensitive and all this may alter her state of consciousness , this love towards my uncle may be a relief for her from all this and will set her heart at peace. So I apologized to my mother and she forgave me. I used to pray to Allah to increase my love towards my mother and help me to obey her. I doubt that if the situation continues as such, it will create huge problems in our family.
1. Is what she is doing acceptable based on her situation?
2. If no, how can I make my mother understand the consequences she is going to face because of this in this life and in the hereafter, in such a way that it won't hurt her feelings.
3. Is it harm for me to obey my mother in some matters where I doubt or I am sure that she uses it for the purpose of pleasing my uncle. If so, How can I tell her that I can't do it.
4. As there was some argument and difference of opinion between me and my mother on this matter , how can I please her and acquire Allah's love.
