I understand. I'm in the exact same boat. For me the boundary was/is enforced by telling ww that I can't be your friend and all communication from here forward is strictly about the kids. A friend wouldn't lie, cheat and disrespect me like you are doing and until that changes, there's nothing more I have to offer.
Right now she may feel she doesn't want to be with you anymore, but overtime she may not be comfortable no longer having you in her life period. That loss could be the start of her reevaluating anything.
I've had to cut friends out of my life based on my values and their actions. This is no different. Sometimes those talks became a wake up call and overtime their lives changed because they wanted to and were better friends because of it.
The ones that didn't I no longer worry or wonder about.
Your call but for me the talk was more about setting the stage for what our interactions will be like moving forward and why. Without trying to make her feel guilty or being angry.
Then, just follow through on your actions. But again, it's your call. Helped me, but you'd have to see if it would for u
