Many of you were probably diagnosed by a doctor with BPD but were any of you told by friend/family member / SO that they seriously felt you had BPD and to look into it?

What would the best way be for them to tell you they think you have BPD?

Do they have to figure it out on their own somehow?

I sometimes wish I could find a way to tell my BPD ex that she definitely has BPD (my therapist 100% believes it based on her behavior), but I have a strict No Contact rule to keep her away. I wish my ex knew she had BPD so she could be mindful about it on a daily basis and get treatment for it. Otherwise we can never be friends.
