Hi Notwillful,
I'm so sorry for this stressful situation! I can only imagine the shock you are left feeling. Did you anticipate that this was going to happen? What do you think has led up to this sudden move on her part?
She is staying with her sister who thinks think im an ass for suggesting BPD.
Have you felt that your wife has BPD? Did you tell her this or only her sister? What types of behaviors does she show that cause you to think this?
I'm very glad that you are reaching out to a T. This can be a tough journey, and finding a support group through this site as well as in T is very good.
