Hello, BlueSky99 &

I'm really sorry that things are so difficult for you with your wife, and I do know that so many of us on this site can understand what you are going through. I'm very glad you've found us!
How did your trip back home go? Did you have a good visit with your daughter? Has your wife returned? How are things going with her now? You are very right that sometimes we just have to accept things about our BPD loved one that won't change, and try to live with that. It's called "Radical Acceptance" and if we can get to a place where we can detach from the hurt of certain BPD behaviors and move on--while taking care of our own needs in ways that work in the marriage--things can actually get a bit better... .
Have you had the chance to check out all of the links to the right-hand side of this page? It really can help us when we get a better understanding of how our BPD loved one's mind works, and learn some of the communication tools and techniques that help us to a more peaceful relationship.
My thought is that I have expended a lot of energy trying to change this situation, but in the end, it's not going to change. I need to come to terms with the fact that this is the quality of the marriage I am in, and to expect more is just going to lead to more hurt and frustration. I'm thinking that I need to try to improve things where I can, but in the end, I need to just accept that she doesn't have anything more than this to give. Do you think I'm on the right track with this approach?
I do think that you are on the right track here, and finding this site is another step in the right direction How are things today, BlueSky99? We're here for you, and want to help
