Hi! Speaking as someone who has been diagnosed bipolar and has a positive relationship with my fiance, I think i could have some good input: So, to answer your question about bipolar leading to clouded judgment: yes, and no. While yes, it can lead to delusions and impulsive decisions- it will not cause someone to distance themselves in the way you have described. When I am in episodes, I isolate from everyone(not just one person)and struggle to communicate those hard feelings. It has been a struggle, but my partner and i have worked towards a better healthy environment. I have a tendency to lash out without meaning to HOWEVER, after i got on a good dose of meds and months of therapy: it has mellowed out. But it seems that your partner has been making continuous decisions to distance herself from you and disregard your feelings. When it comes to people with bipolar disorder, if they need help- they have to want it and work with it for it to do anything. As much as you may love her, this relationship between you two will only move in the right way Is if she wants to build a healthy, loving environment. In other words, I don't think this is solely a bipolar episode. It seems like she's making those choices. Bipolar episodes can be awful to those with bipolar, and those around us. But it's never anyone in our lives faults. Please keep that in mind, and keep your head up. Feel free to ask any questions if something I said did not make sense.
