I agree with Ann O' Connell ’s points.
Kitty, your choice with how to deal with trauma from an abusive parent is valid, but so are other responses. I have a child the same age as the writer you’re criticizing, and if it was me, it’s hard to imagine even letting that abusive person into my home with my daughter, even for visits, much less to live with me for months. I don’t say this to judge her decision to do so, but rather to point out there are many perspectives on how to handle such a thing.
I think that writer has gone above and beyond to get her mother help, while also raising her child and supporting her as a single mom. I see incredible strength in that. And so much love.
Her writing has always been vulnerable, and her honest stories are helpful to many struggling with being in the sandwich generation and processing abusive childhoods. I don’t believe she should be silent about the difficult realities, and I have never found her honesty to be callous.
The love you continue to show your family is admirable, but it’s not the only way.
