She's too young

I am 23 years old, married and working on having a little family of my own, one day. I was with my now husband for about 5-6 months before he asked me to marry him. We had a year and a half long engagement, and was married on August 18/2012.
So if I have done the math right,  I was 20 years old and engaged and was married about 6 after my 22nd birthday.
The day I told my mom and sister about being engaged, they seemed to be happy. Some of my friends were down and others not so much. But the biggest question that people asked was "Are You Ready?". Now I know for sure everyone is asked this question, but I also know when you're younger... That question means so much more.
Right after my 21st birthday, I started to plan more and more. Mr.Reid and I started marriage counseling with my uncle/pastor. Working overtime to pay for this and that. Anyway, one day a friend of the family came up to me and asked me "was I ready to be someone's wife?". I told her "yes" and then she hit me with a conversation from no were.
She told me she had been married young and it didn't workout. That she only married him because, she didn't think it took as much work as it did. She went on and said, " you're only 21, and you have so much life to live. You have no idea how to be someone's wife. With y'all being young, the road to failing is closer than you two think." At that point I was done talking to her because I didn't want to hear the negative things she was saying. Fast forward to now. Mr.Reid will be 27 this September and it seems like people still are on that question.
So now I think I can answer this question without any problems.
It is people in this world that have gotten married and had children all before the age of 20. And has made it to see 30-40+ year of marriage. Some places in the world the age of marriage is 10years of age. It is no right or wrong way to be a husband or wife. For one it up to that couple, the rules of that relationship and the way they want to love each other. If being young and not having money was going to really mess up a marriage, someone should have a talk with the 30 and over people, who are on marriage number 2 or 3. Talk to all the rich people in the world who can't seem to get it right. Hell Kim.K has money and was over the age of 30 and only made it 72 day or something like that. I guess that put holes all in your idea.
People have to understand that people, relationships,and marriages are all very different. Some people have open relationships and marriages( it isn't for me, but who am I to tell them, they aren't going to work.)
I know it's doctors out here who study, young marriages and say 'She is too Young' but are you God? Can you see the future? No! I didn't think so. So who are they to tell me or anyone else for that matter,  they will not last because they don't love like you think they should.
So for all my 20 somethings if you're in love and want to get married, go to marriage counseling to make sure you this is what you want and go for it. No one else is in the relationship or marriage, go be happy.
