I wonder

I am getting married! Yupz, to the man of my dreams. But in the midst of the preparation, I wonder if I have made the right choice by agreeing to be married so early. Perhaps if I allow him more time to mature, he will, like wine, become nicer and nice and more flavourful. He seems to me like a young boy, yes, sometimes matured, sometimes not. Am I too idealistic to hope that he matures fully?
Then i examine myself. What about me? Am I matured enough? Will I be able to cope with the rigours of marriage? "Rigours"? Shouldn't marriage be something to look forward to and be ready for it?
I don't know at all now......
