As You can see in bold text in first two phases of human psychological development our spouses can stuck in:
a) the containment/nurturance (i.e., the maternal, or in Neumann’s terminology the “matriarchal”) stage,
b) the adapting/adjusting (i.e., the paternal, or, again in Neumann’s terminology, the “patriarchal”) stage
So, they never finished first and second phase, or never finish second one. When they reach last stage which should be in middle age, they can't go forward, so they have to go backward to finish one or both of them. I believe that my wife regress in second stage then that does not solve problems, and now I believe that she is in first stage, act and show up as girl, 2012, 2013 as teenager. 2014 is little girl. I have to say that she is much bearable as little girl. So, OM stuff diminish. If she solve first stage issues hopefully then she should (?) go again in second and try solve that, then OM will show up again (?), I don't like this !!! So, long path she have to travel...
