Hi, Any advice for this

I'm K and I'm mixed. I'm Dominican and Trinidadian (right, strange combo)  my boyfriend is mexican. WE HAVE HUGE cultural gaps. I grew up primarily with my mother (who is Trinidadian) and learned to live a pretty American lifestyle with dashes of my cultures thrown in. But my boyfriend is fully mexican....eats, sleeps and breathes the mexican way. How to we blend the two, were afraid we won't be able to teach our mixed child the best parts of both cultures. How can we?
