Ok...why the heck you two break up? This book is more likely a summed up collection to answer this question from a lot of aspects, even details.
Infantile sexuality is one thing, sexuality as solo drive of every problem is another, and attitude to religion is a bonus bombing. I think, basically, isn't it type problem? He questions himself as well, "what is truth?", it is both what one observes and what one expresses, both of which are subjective in fact (according to Kant), despite of the fact that the subjective elements are just one piece that included in the tremendous objective nature. Yeah, he is really tricky by firstly defining his understanding of the term of "truth" which exempted him from being criticized as "subjective" because truth in fact is more or less subjective itself.
Jung believes the perspective and method of Freud does nothing more than "paddling about in this flooded country". Jung also believes he "prefers to look at man in the light of what in him is healthy and sound, and to free the sick man from just that kind of psychology which colors every page Freud has written", by "that kind of psychology" is what Freud asserts to have no way out and be even a germ of the birth of individuality (see in the discussion on incest prohibition his book Totem and Taboo).
Damming up of libido, stagnation of life, psychic conflicts and neurosis, there are fixation on infantile issues or family romance/parents complex, sexuality and will to power, instincts and spirits, though both of latter whose nature remain hidden, those pair of opposites are always in conflicts, forcing life into eternal chaos.
Therefore, he takes advantage of chaos, because chaos is also an sign of liveness and change. He believes things can change and must change, because nothing is out there without dynamics, even the change to the is not permanent and will relapse, the change is still there, the canal of libido must be opened, because life must be lived, balance must be achieved, order must born and obeyed, that part is also human nature as well (It can be explained and proved by his method, he follows the patient's fantasy instead of terminating it, which in some cases, may seem to worsen the symptom at early stages of treatment).
I don't know, he reminds me of Sisyphus in some degree.

and that "The Significance of the Father in the Destiny of the Individual" is rather awesome, as a person with not so good childhood family memories and still find myself hard to forgive one of my parents, I recommend anyone who has the same problem just read it. It helps :)
