Marriage? Two or more than Two?

Just finish watching Sex and the City 2, my mind just can't stop thinking how will our marriage be.
2 people or more than 2?
what our life will be?
will I get the things that I want? and am I dare and brave enough to strike it?
will he be as romantic as I wish?
will he be as understanding as the guy in the movie?
will our marriage be forever?
will we be happy ever after?
is he thinking as what I'm thinking?
