Mum spreads lies and discord between siblings and to our relatives
My mum like to spread lies and discord between me and my 3 siblings sisters. Basically 4 of us have not been in good terms especially after we have our own families.
This is made worst by the fact that my wife and my mother cannot get along and she complain to them at the slightest provocation even with my wife giving in to her wimps and fancy. But she is still sour about my in laws taking care of my kids and a united family.
Many years ago my mum willed the current house she is staying to me. This cause some discernment among my sisters and last year my mum told them about the will and I am like outcast in the family. Last year due to covid restriction I was not included in the reunion dinner any my family of 5 eat ourselves. I invited my mum to join us but she rejected and have reunion dinner with my sisters. Subsequently she sold her house and downgrade to one bedroom condo and it was not will to me.
Although sometimes I might be rude to her but I still gave her monthly allowances and Included her in my family activities.
Recently, she have been updating some relatives of our personal family things. When we found out and confront her she denied everything.
I am embarrassed by her spreading lies and twisting and turning the facts to make me look bad and things that have already past 20 years ago she will dig out and say although it is factual. Some relatives that was not familiar and some listen to one sided stories especially family event they will look at me with colored eyes and judge me by what my mother say, her stories.
How do I overcome this?
