Marcusko,
My wife was very loving and family oriented for 1 st 20 yrs of marriage. Here is some approx timeline things:
Career woman early 20's. After 2nd child went part time.
resumed career partime - full time mid 30's. last kid at 32.
started going out more around 36-37.
career resumed moved up and a couple promotions.
working out, plastice surgery, dressing younger late 30's
promoted to Asst CEO at 43
bomb drop March 2010
the self centeredness started a while back, but for a time it actaully enhanced our marriage or I was totally blind but:
