All, I was able to defuse the situation. I validated her feelings about the situation and she told me how happy she was that I did that. Often times I try to prove my point because I hate when my words and actions get turned into something else. The lessons worked! At least for this instance. Thanks!
Good that you talked!
I think there is more in the story. Buyers regret is common with pwBPD. For you it make be worth considering how you as an individual and as a couple make decisions. How you take and weight her input. When you got the offer you asked her for her feedback and she was excited. The problem here can be that at any point in time you get either extreme good or extreme bad from her. Basing your decisions on this feedback is going to a slot machine for input. A more dialectical approach with maybe two separate sessions one for the the positive side and one for what is not so good can give a more balanced picture. There is value in the thinking and intuition of our partners - it is up to us to unlock it.
