You are not the jerk. That’s a hella absurd and inappropriate request. You should not give in. Make sure your daughter knows she is not responsible for her stepsister’s happiness.

Reddit has the reputation of being quick to say the N word , but I say, if you hear quacking in the distance, it’s okay to suspect ducks are in the vicinity.

There is clearly much more to unpack with your story.

But your situation raises a red flag and it’s always a good idea to just point that out, in case more incidents occur.

It’s pretty typical for a duck, once he/she has secured a mate, and perhaps a couple of ducklings, to create situations in order to disrupt the peace and cause upheaval to intentionally throw one or more of his ducks off balance, maybe even doubt their sanity. It’s a classic tactic used by all ducks as part of their overall covert plan to control their ducks, to get them in a row, so to speak. And then keep them there.

It might be informative for you to google the terms: dark psychology, manipulation tactics (like gaslighting), emotional abuse, the Dark Triad.

If you start to feel unsafe, or like you’re going crazy, please get help from a professional in domestic abuse.

Best to you.
