Being married is by far the best thing to happen - "if we are looking at" - singleton vs. married life.
When you are single there are all kinds of freedom to experiment. However, even that gets boring after a while and you "crave" for true companionship. Otherwise, deep down you feel lonely.
If you are married, there is NEVER "loneliness". There is ALWAYS someone waiting for you. Looking out for you and wanting to share the rest of the "after work" time with you.
So married life is definitely better.

As far as problems issue - well it depends on family to family. So always put your best foot forward and enjoy each day.
And there's always someone to fight n argue with(hoping they won't leave u for that) incase u get bored with all lovey dovey felings. :) marriage life is never monotonous..lots of drama more than life 1.
