Hi bpbreakout,
the two are not so easy to differentiate. As Bipolar can be tackled with medication while BPD thanks to the "PD" has more a stigma and is harder to tackle the deck is stacked for an initial bipolar diagnosis. I wished the deck was stacked towards a diagnosis associated with a DBT treatment with little side effects (besides learning to cope better everywhere).
Both - getting maybe off eventually the continuous medication and learning techniques to be more effective in life are positive facts. It is also understandable that you are afraid of her changing quickly when taken off medication. Ultimately it is between her and the T. Have you shared your concerns with her?
I don't see a point in getting involved in a debate about whether wife is bipolar or borderline or both.
If it is BPD it has a tendency to affect the whole relationship and the partner to a great deal... .
