Should Borderline Personality Disordered people tell future mates that they have diagnosis and what it means?

With so much self-sabotage after the honeymoon phase (i.e. infidelity, suicidal gestures, raging, moodiness, someone dual personalities that turn off and on within minutes or hours aand even cutting and hair pulling of one's self). Should you tell a prospective partner that you have this mental illness or should you stay in therapy and just hope that therapy cures it before the next relationship is destroyed? Bear in mind, every relationship has been destroyed through due to having BPD. It is a personal unavoidable history, but is it the future? My therapist is providing a good therapeutic bond, but admittedly knows little to nothing about BPD treatments other than CBT.
