Hi mentalize

I'm sorry to hear this.
When I have tried to address her illness with her, I am generally met with extreme resistance, defensiveness, hostility. It's brutal. I feel that it is unsafe to voice my opinions and feelings about certain things.
We do not recommend that you tell a loved one that you suspect that they have Borderline Personality Disorder.
We may think that our loved one will rush into therapy to conquer their demons, but this usually doesn't happen.
Instead, this is difficult advice to receive and more likely to sound critical and shaming (e.g., you are defective) and incite defensiveness, and break down the relationship trust.
