Hi Annieface,
I wanted to point out the dysfunctional dance your stbxh is doing. Instead of keeping things between the 2 of you he is pulling other people into your divorce and creating a triangle.
https://bpdfamily.com/message_board/index.php?topic=108440.0The triangle can vary depending on your perspective.
To Him... .
You are the persecutor
He is the victim
Family Members are the rescuers
To you... .
You are the victim
He is the persecutor
Family Members are the rescuers (or they can also be persecutors)
My thought about your situation is rather than trying to prove or show the behaviors you see in your stbx, how about trying to move yourself off the triangle.
Frankly in a polite way ask them to butt out and when someone asks you about it be polite but don't discuss it.
Cousin so and so want's to know the latest on the divorce, could you say something like... .I appreciate your concern but I'm not comfortable discussing it... .I know you love both stbxh and me and want to see us happy and I appreciate that but this is between the two of us... .I really don't want to discuss my divorce or stbxh right now, I could really do with a little bit of fun, shopping therapy, a distraction from it all now... .
Create a boundary for yourself that you will not discuss it with them. You can only control what you do and by not discussing the divorce with these folks you have removed yourself from the triangle, by not talking about it you don't have to listen to the FOG (Fear, Obligation, Guilt) that your husband is sending via your family members, you do not need to justify your reasons for divorcing to them, this puts the divorce discussion back where it should be between you and your stbxh and ultimately by not discussing it with others you are taking power the away from him... .using your family to get to you is no longer working.
In terms of what your family believe, they will believe what they are going to believe. They know you both and will make their choices regarding the two of you as they will. Some will support you, some him, some both, and still others will stay out of it... .It's like that in every divorce and we can't control that, it will all shake out during and after the divorce.
