Hi! I believe I can be of help to you with this issue.
First, let me say I have dealt with Borderline Personality Disorder (BPD) from my internship on in my private practice and here online. But your question is truly unique in my experience. You are being so very honest without hiding behind any defenses. I am truly pleased to have made your acquaintance.
I can see from what you write how painful this is to you. And I accept your diagnosis for Michael of BPD. Though I have to say that your description seems more consistent with Narcissistic Personality Disorder (NPD). NPD can form, according to our current thinking in the field, in the age bracket you refer to (early infancy through toddler years). And his behavior seems narcissistic.
But our question is how to proceed. And I want to suggest that you avoid the all or nothing, 100% or 0% thinking that I'm sensing you're considering. You know that kind of thinking is BPD kind of thinking, black or white. So rather than no contact at all, I am searching for the right TYPE of contact.
I'm wondering in fact about emailing Michael our discussion. Letting him read your feelings and my response. Now if he has NPD, this may not be a good idea. Because narcissists can't handle anything that might seem like it puts them in a bad light. Even if it is not intended that way they can fly off the handle. So you will have to decide.
Because one way to have a relationship if BPD is what he is suffering from, is to have a more remote relationship. Where you can see pictures of the grandkids and YouTube videos of his family perhaps. I understand that the family dynamic in his family is strained. Again it sounds narcissistic. So this may not be worthwhile if it is.
The idea is that you maintain some way to connect with each other in a safe manner for both of you. If he needs to vent (BPD) or if he needs to condemn (NPD), having it be written in an email is so much better because you don't have to read the whole thing and you can respond at your own pace.
So let's look at some books on both BPD and NPD and you can use them if you wish to try to sort out what Micheal has. Randi Kreger wrote a book you will find in the library though it's very popular and may be checked out. So you may want to buy it online. It is called Stop Walking on Eggshells. Her is the American Amazon page for it:
She also has a wonderful online group called the Oz Online Community for Family Members. You need to really get to know her resources because they'll help you. She's a very nice person, too. Here's the web page:
For learning about NPD, these books WILL help you as they have been tried and I've seen them have good effect if you follow the suggestions of the authors:
1. The Wizard of Oz and Other Narcissists: Coping with the One-Way Relationship by Eleanor Payson. This is a great book that will help you with the lack of self-esteem that living with a narcissist or being close with a narcissist will do to you. Amazon:
2. The Object of My Affection is in My Reflection: Coping with Narcissists by Rokelle Lerner. This book is newer but is extremely clear and insightful and has helped people since it came out 2 years ago. Amazon:
Okay, I wish you the very, very best!
