Jeansok,
This post started off as something else (I was asking for book recommendations for husband for DBT that didn't mention BPD). Fortunately I was informed that giving him a self help book would likely be perceived as invalidating... . and it rolled off into this discussion (I was desperately looking for a way to stop the beratings).
It was heartbreaking actually. I would just sit there and listen and listen while my uBPDh tore me to shreads every morning. I am a professional woman (with a high stress, high powered job)... . and I couldn't even walk away when my husband (who does a much less intense job) called me a STUPID piece of _____. Often my son (a toddler) would be sitting there too. I felt paralyzed. I knew enough not to JADE... . but not had tried over and over to implement boundaries and it wasn't working.
When I am implementing boundaries I am a strong, competent woman, good mother, good friend, good wife, good lover etc. When I'm acting co-dependent... . well my whole life seems to fall apart.
I believe that Grey Kitty changed the name of the post and chopped some of the less relevant stuff out of it... .
So... . the most important things that I learned here was:
1. boundaries must be implemented with consistency otherwise it is much more difficult to get the effect.
2. it doesn't matter whether my spouse has 'buy in'. Focus on what is important to me. In fact telling him about the boundary may just be an invitation to him 'to break the rules'. You can work this stuff right in the moment.
3. Some people walk away without saying anything (and it works for them) but I don't think that its fair to my spouse personally. If someone was going to walk out on me in the middle of a discussion then the least they could do is tell me why. 'I am leaving this discussion because at this point I am worried that I will say something I regret.'
4. Start small. Its hard for my uBPDh to understand why what normally works isn't working and like a toddler he will throw a tantrum. For me - I narrowed it down to two things both related to Verbal abuse
1. When he starts calling me names
2. When he starts telling me why I am the scum of the earth (should never have been born - stupid, disorganized, etc.) I decided that I would have two strategies - one for in the house and one for in the car.
For the house - if he starts up I say "please don't speak to me like that. If you do, you can finish your own ______ (fill in blank here)." Our scenarios usually involved me making breakfast or packing his lunch. For some reason a lot of times I got paralyzed because I didn't want him going to work without his meals... . Kind of twisted. He is saying the worst most horrible things to me and I am worrying about him not having a sandwich at lunch. CODEPENDENT cough. My husband is a competent man... . if I stop in the middle of making him breakfast or lunch he is TOTALLY capable of 1. finishing it. 2. making something else. 3. buying something out!
For the car - if he starts driving with road rage. Calling me names etc... . then I tell him "if you keep speaking to me like this then please pull over and leave me by the side of the road." I started carrying a purse again with a charged phone, cash, etc in it and spoke to one of my friends to warn her that I may be sitting on the side of the road and need a ride

I hear that its important in a car not to provoke them more. This boundary seems to be working for us because frankly my husband is totally paranoid about my safety and I am VERY important to him. The LAST thing that he wants to do is leave me on the side of the road where he can't protect me (IRONIC isn't it).
I couple of years ago I thought my husband was NPD and I found a self help book online that talked about boundaries -- but the biggest thing that kept it from working was that I kept saying to him "You cannot treat me like this." and he saw it as an invitation to prove that he could. Now I realize that he can treat me however he wants to... . but that doesn't mean I need to accept it.
Sorry for the novel but it was actually a good recap for me. I hope you get something out of it.
