Zuko: my dad and sister are mean but at least my mom loves me :D
Ursa, who lied to Ozai about the true identity of Zuko’s father for selfish reasons, causing Ozai to hate Zuko and then she poisoned and killed Firelord Azulon before running away, leaving Ozai as the new Firelord of the most powerful nation in the world and then used a spirit to change her face and have all her memories of Zuko removed so she wouldn’t have to live with the knowledge that she left her children with an abusive parent and then married her ex boyfriend who she had an emotional affair with and now has a child with all while Zuko is now banished and living his worst life:

tfw you can’t say sike 😔🙏
Most of this isn't true. Ursa suspected that Ozai was intercepting her letters to home, so she wrote a fake letter saying that Ozai wasn't Zuko's father. When Ozai confronted her about it, she knew that he really was spying on her and explained it was just a trick. Ozai really is Zuko's father. She never had an affair, emotional or otherwise.
And she didn't run away on purpose, she was banished for treason after killing Fire Lord Azulon. It's not like she had a choice. So she returned to her hometown and started a new life with her old boyfriend, but her pain was so great that the Lady of Faces (a spirit from the spirit world) offered to give her a new face and erase her old memories, which she accepted.
Ursa's story is great because, like all of ATLA, she's a full character who makes tough decisions that have real ramifications. She loved Zuko enough to kill Azulon (because he'd ordered Zuko executed) and save his life, even though it would mean leaving her favorite child. Everything she does after that is an understandable choice for a grieving mother. Could you really blame her for accepting a new face and new memories after all she'd been through? Maybe it wasn't the right choice, but I understand it and that's what makes ATLA so special
I think it should also be mentioned that she was forcefully taken from her home village when ozai picked her as his bride. She had no intention of leaving her boyfriend but ozai was gonna have him killed unless she went with him.
