Is this wrong of me?

My mom got my kids a slew of gifts for Xmas. Its her way of "apologizing " without really doing so.

Some days ago she accused me of not loving Mt daughter bc I sent her to her dad's for *two* days 🙄 said she wint have nothing to do with me. Told me I half ass take care of Mt kids and more.. I also remember her telling me to give away the Xmas gifts I got her last year.

Naturally I dont want to walk to her. But she keeps trying to engage me and gets pissed when I could care less.

Am I being an asshole?
