Friendships after marriage

All you married couples out there, did friendships you had prior to getting married change after you got married? I feel like the people in my life completely changed, as if I dont even know them anymore and it all started after I got married. I'm the same person, do everything the same and treat everyone the same as I did prior to getting married, only differnce is we are now in different stages in life (but that doesnt bug me, maybe them)?! But, anywho I was just curious if others have experienced similiar or not.
