You two will not be able to share the childhood like a couple who grow up from the same culture. However, you two can enjoy the different childhood, just like comparing the notes, like one would say, I did this, this, this when I was young, and another person would say, Oh really, I did somthing else instead. It depands on which kind of shareing you enjoy.
When you find someone you like/love, just think about what kind of marriage life you want the most? Listen to your heart close. You will find the answer. Kind of cliche:) But still hope it helps...
