Hi AG,
I would be happy to give you some insight on what that would look like. My exBPDbf dumped me and ran back to his (also BPD) spouse (don't ask). These two "lovebirds" have been together now for 25 years.
Some of the incidents are as follows:
While my ex was sleeping in his recliner - spouse came up behind him and punched him in the face. The blow broke his nose.
When they were at a local chain restaurant - my ex gave up one of his "two for one" drinks to a friend. Spouse didn't like that. She swung at him and knocked him off of his barstool. They were banned from the restaurant.
When they were attending a Superbowl party at his employer's establishment - spouse threw a glass across the room at him.
Spouse has rammed his vehicle with hers on more than one occasion.
The local law enforcement has been called to their home so many times - the police now just laugh and take their sweet time showing up.
My ex and his spouse have not had sex in over thirteen years. She doesn't want him in the bed with her. Told him not to even breathe on her.
She is a raging alcoholic as well. And he stays.
Good times, huh? Yet I am the one that is now "split black" and despised simply because I refused his Facebook "Friend Request" back in December. Yes, I'm serious!
OH! Forgot to add - no one will visit them or invite them to their homes. They've witnessed the behavior first-hand and want no part of the drama. When we became involved - his friends told him to run away with me and never look back. Yeah, that worked out.
