I'm not diagnosed with BPD; however, my ex-girlfriend suffers from the disorder and isn't in treatment. (Instead, she's retreated to another emotionally-dependent relationship with the person with whom she entertained an emotional affair; low self-esteem, no boundaries - you all know how it is.)

I'm seeing a therapist specializing in BPD and attachment disorders. After I disclosed that I had recommended my exwBPD attend  a group DBT session in her region, he encouraged me to research *MBT*. Apparently it's a relatively [new treatment being refined by the Anna Freud NCCF](http://www.annafreud.org/training-research/mentalization-based-treatment-training/about-mbt/) in London.

*I was wondering if anyone here has had experience with this treatment? If so, was your experience positive or negative?*
