Hey Maturin - Very well done IHMO. That is a great example of DBing. You stayed calm, held the line, and survived the evening without taking any bait. You did walk the path of a positive, confident, and disengaged "person" (to take it a step further). You held the boundary as well as you could. You withheld "you" from her: negative reactions, taking the bait, and "feeding her cake". I don't think you necessarily have to sleep in another room given this was a success to me. Now, if you feel differently, you may say something like "I dislike what occurred the other night and felt disrespected. I hope in the future that won't happen again". Note the lack of use of the word "you" in there so that you might sidestep direct provocation. Or "If what happens the other night happens again, I will move to another room" (hopefully with a door that locks though that might not stop someone who is 1) inebriated and 2) determined). Again, you did great. Stories like these help me feel more confident when I'm facing something similar so I am grateful for you sharing yours.
