That phrase usually comes from any controlling females who want to justify their control over the man by saying he's "not the same guy" as if he is made guilty to a crime.And I can already hear her say "he's not the guy I met and fell in love with"... well no duh! You made him that way!
Dunno how you married fellows who have women like this can take it.
All I have was dated. Once I see 'Ms. Control' or 'Scarlett OHara' in her personality, our future together ends RIGHT THERE.
Love is not love if there is control in the mix.
