Couple of things...I agree w/what Steve said above as to what you may be doing to improve things however you asked me here for a specific point of view... Reading what I have read, there is no doubt in my mind your wife has some form of bipolar (I am leaning with II or possibly Unipolar) however that isn't an excuse to drop the bombs she has...
I threw Unipolar in there based on the age at which she was diagnosed (generally later then with Bipolar)...
A person with any of these "polars", myself included is very selfish in their thinking...It is all about them...
"Statements like "I don't know why I am leaving you. I love you so much." don't sound like they are coming from someone simply caught up in an A."
Perfect example...Not only is she caught up in the A, she is also caught up in her own mind...Again that isn't an excuse simply because no matter how imbalanced her mind is, it is treatable - Hence the mood stabilizers...
Now mood stabilizers w/anti-depressants may be the best thing for her - That is what I take now...For a long time I only took a mood stabilizer - Lithium (because I wasn't ever prone to much of the depression side of things)...
I have gotten about 1/2 through your posts and will say I applaud you for the way you have treated your wife with respect concerning her sexual assault...I had the same thing happen to me at 16 and only recently started dealing with it.
Is your wife on meds at this time? (it may say however I started reading at the beginning so I could grasp the whole situation)...I will continue reading/posting as well. I do hope this is helping.
