Thank you for coming back, Frustrated Husband.
Of course, no one knows definitely that her actions are totally motivated by bipolar illness or whether she really has these negative feelings toward you.
We can surmise that part of it is the illness speaking, and part of it may be a certain disillusionment with life at this point.
I don't think anyone was offended by you as a person. I haven't posted to anyone who appears more genuine and honest in his feelings than you are.
I wish you much success and peace along your journey in life. I
hope you and your wife like your psychiatrists; that's very important for your healing, in my view.
Good wishes to you all; take care of those precious little children.
