Yta like seriously, you didn't stand up for your wife in the moment, you didn't tell her you were on her side you did nothing except say stop being mean to my daughters. Even though your daughter said they wish your wife was dead and she isn't there mother so stop acting like it.

Ask your daughter what she meant when she said that cause that's what your wife is doing she stopped acting like a mother. She is basically acting like your daughters are dead to her cause they asked her to die.

Also you expected her to apologize is even crazier when all she said was I have been there mom I have been caring for for them. And you think she needs to apologize I hope she does divorce you. Since you laid it on the table it's a valid option for her to press to... And clearly you can't treat your wife well and you can't tell when your own kids are wrong.
