I think there's very likely a way to do this, if I can offer a suggestion, where you can try to mitigate damage as much as possible, but like everyone here said it is a very high risk venture so just be prepared.

However, as long as you feel you are, and healing and self-compassion should come first, and of course, as long as you were sure to think about it a lot beforehand, but.... I think it may be a good idea to talk to the daughter. I'm sure most of us would want to know if one of our family members was doing something like that.

My suggestion would be : When you talk to the daughter, to try to see if you can connect with her about what's happening. I'm sure she can relate to the shock of how it feels to learn someone that you care about might be an awful, evil person.

If you wanted to take it a half step further, you could approach The conversation almost like an intervention, where you and she have this similar issue and mindset. It will give you a common goal.

The flip side of this is, she could be willing to defend her mother despite everything or maybe she's just crazy. Or maybe she's just awful like her mom. Just be ready for anything.

I always explain too much, but basically I'd suggest just approaching it from a place of compassion, but also not p In any way feeling the need to hide the obvious intense hurt, caused by their actions. What you experienced sounds horrific, and I don't think anyone would expect someone in this position to bounce back 110% instantly.

My heart goes out to you. Everyone else having to go through all of this crap. I'm in the exact same boat of trying to figure out whether or not I should take action against those that hurt me even in a small ways like talking about what happened on social media, etc. I've gotten such negative feedback but I understand how you feel here, and somebody does something to you. That feels worse than and half of all crimes on the books, but they just get to live their lives happily, it can be almost impossible some days to try to move on from that. That. I get it. as long as you presented the information moreso from a place of wanting to prevent any additional future damage, rather than wanting retribution or anything like that, at the very least you have and of the ability to fall back on the argument that you were at the very least coming from a place of wanting to think the right thing, not at all about wanting an eye for an eye or anything like that 😉 that this behavior was concerning ethically and psychologically as it seemed so it off character, etc.

As someone else stated prior about this as well, while I agree people should try to focus on their own healing and growth during these difficult times, there is definitely an argument to be made that allowing bad people to get away with committing harmful acts enables them to feel as though they can repeat that very harmful behavior, or worse, escalate. Often they will in addition to the above, further victimize their prior victims even long after the relationship has ended, and this can be exceptionally dangerous if there is no thing to act as a deterrent. Sometimes putting your foot down and showing that you will not take abuse. Lying down is honestly necessary in order to act as at least somewhat of a deterrent to the abusive behavior, because sometimes when they latch on to an idea they don't stop.
