I think it a little of both.  Not one is mutually exclusive.  Someone told me that love is also about loving someone in spite of their quirks and differences.  I don’t find those differences in my wife something I want to spend the rest of my life with.  I feel we have evolved into 2 different people.  My needs are different.  Thinking logically, I wonder if the depression along with my medication has changed me enough to change my personality that me wants/needs/goals are different because of the chemical changes in my brain.  What do you guys think?  Does this sound farfetched?
