I agree with the people who said that there's no worries about the spouse knowing the tactics in case of a "next time," because if there's a next time, I am fo' sho' gone. I made that very clear to my H, that if he's dissatisfied or has a problem with me or our marriage, he is to be a big boy and talk to me instead of holding on to it and then falling into an EA with some tramp.
The thing about DBing is that, on the surface, it seems to be about manipulation, and I suspect some people enter into the practice with that in mind. However, truly applied, it is a reflective process that taught me how to detach from expectations, communicate better, set boundaries, and become happy with myself. I wanted H to remove his head from his buttocks, but I'd reached the point where it was just peachy if he didn't. I was okay with ME.
