My advice - read NONE of the articles from gettinbetter, it's filled with generalized anecdotes, fear tactics, misinterpretations, and it has seemingly no useful advice. Instead, read things that will actually improve your relationship: When Hope is Not Enough, The High-Conflict Couple, Stop Walking on Eggshells, and Overcoming Borderline Personality Disorder.
gettinbetter could be useful if you need emotional validation, but as far as I've seen, the information on the site is uniformly garbage.
