You are then one of the ones who got nicely working marriage, and that is good thing and I am sincerely happy for you.
As I wrote you can choose any path and be happy, but what I have seen near me marriage is usually good some time and then it goes baaaaad. And when it goes bad it goes really bad and can get ugly fast. Divorce, sharing kids and property, yelling etc etc. Its not funny when it happens and I hope you are lucky to go happily untill end.
I am myself keeping away from marriage and kids, maybe time will come later, maybe not. But now I am happy to be able to have my hobbies and myself at first place in my life.
Remember people you can do anything you want with your life, don't let other people tell you what is right way to live. I have seen people who has been forced by society or families to do different things, including marriage, some special school(musical), making children, etc, I think it is sad.
