Thank you.

Your mother has made you buy into her poor excuses to meddle into your life.

What type of discrimination does she get, where do you all live. The worst person discriminated against for race, sex, looks, gets a job, She does not have a job because she has been too lazy or busy running your life to do something productive with her own life.

Has not remarried, OK perhaps she prefers not to marry again. Since if she did want to date or remarry she could, I have lost 2 wives and I am not good looking, and never had a issue finding a new partner because I looked for one.

Your mom is alone and not working because she prefers that, perhaps it gives her a reason to complain and expect others to take care of her. You by perhaps paying her bills ( someone has to pay them unless she is just rich) enables or allows her to do this.

It is easy, start with some ground rules, not all of them to start with, but perhaps your education, or perhaps who you date. Tell her that you will no longer discuss these with her if she will talk negative to you about them. And if she starts, end the talk, leave if you don't live with her, hang up the phone if on the phone,

It is easy, you start controlling the talks with her.
