Hi David

It sounds like you’re more concerned about her harassing your job and family than you are about both of your personal needs.

Perhaps there is a compromise somewhere in between answering her calls and texts, allowing her to freely vent and blocking her?

Would you be comfortable with saying something short politely setting your boundaries then ending a call? Similarly texting something short politely setting your boundaries could be a strategy.

She would likely be upset by the change but with repetition she would get used to it.

It would be important for the message to address her concerns about these new boundaries, apologise and recognise that this current relationship is unhealthy for both of you.

Are there any other strategies that you can think of?
