My wife was diagnosed with BP around 20 years ago. She didn't accept she had BP and that she had to do something about it until about 5 years ago. In those last five years things have completely turned around and we can now answer yes to all five questions. She will always have to deal with BP, but it is no longer the central fact of our lives. It took my wife 20 years from diagnosis to stability.
Some people never make it.
These are hard questions. The real truth is that love is not enough . To be married to a BP is a difficult path and no one will fault you for dropping out. But you must decide.
