Hi there,
as a fellow suffering significant other (welll....Actually he is now out of my life, due to the lies) I soooo understand what u are going through!! I wish I would have been able to get some support earlier...Perhaps I would hve saved myself a whole lot of pain, but what ifs are pointless.
So your spouse hasn't actually been diagnosed?? If that is the case, she obviously isn't being treated, correct? As far as advise, protect yourself!!! Don't fall into the trap of believing based on your emotions. Set bounderies, and try to stick with them for your protection. Educate yourself about the disorder, and mental disorders in general. It is what finally made me able to 'see', and learn the truth I sooooo wanted to avoid. But we can be lied to for just so long, be used for just so long, be stripped of our dedication. I certainly didn't want to make the choice I made, but for my own sanity, I had to close the door, because his lies and deciept reached a level I could no longer accept.
Without more info I can only have my opinion. But...Even if there is a diagnosis in place, it sounds to me like there is more than just the bi polor issues. I have several awesome sites with info if you are interested. Let me know, it is very painful caring for someone who is bi polar/borderline, or any other mental illness....It just plain hurts.
Best of luck to you,
cor
