i did not watch the show but i read the article on oprahs website...i also read the article in runners mag...
my $0.02:

the whining spewed out even in text...in a society where marriage has become so disposable it is such a shame we have an icon of a woman {oprah} saying "that is exactly why i have not married, and probably will not" for such a strong, successful woman it makes me sad to hear her say that! i am a divorcee and have thoughts of regret...and wish someone had shook me and made me look at my ex for what he really was i would not have lost those 3 years (yeah, i do consider myself lucky it was ONLY 3 years...could've been more) he was verbally abusive and it was leading more and more to physically...i got out!!! that experience did make me look at marriage a whole lot differently!!!
my second marriage (4 wonderful months so far) i put lines in the sand...gave ultimatums...put my foot down...and voiced my goals, wants & needs......BUT you know what??? SO DID HE!!! because i truely believe in give and take we have compromised so little of ourselves yet have given ALL of ourselves to each other!!!
i am not sure my point to all of this is... i just hope that girls in the threshold of marriage would not shy away from the whole thing but understand they do not have to loose themselves to the other person...but continue to be the person they fell in love with...and grow together!!!

btw: cause i am such a mushy romantic...what about this ending...(lance & kristin live 2 miles apart) because he has retired from cycling and altho his new passion is as time consuming he still makes a point to be with his children...do you think by some glimmer they might make amends and be a happy family??? maybe??? does anyone else have this little hope??? now...THAT would make me cry
