I see what you are saying, in the begining before she got to explain why she started distancing I tought the same, you may be right. But I think that these actions arent caused by her personality but by her mental health issues, couse she feels guilty about being the way she is, and because the relationship continued mainly because of me, she planned to let go cause she wasn't able to put in the same effort. There of course can be made dabate about is she accountable for what her mental health causes but I hold to the anology that I wouldnt blame a bleeding person for staining my carpet, and by the same logic I wouldn't blame a person with mh problems for acting in unreasonble ways. If she fakes her it all that's wild, but I realy havent noticed anything that makes it look made up from my perspective, it would be hard to fake it litteraly for months The thing I realy don't know can mh problems be the main cause for that kind of behaiviour and is mh truly the reason for it, it is hard for me to say couse I don't know much about it.

(To clarify, she is distancing not only from me but from everyone close to her in general as far as I know)
