Yes. Though my Dad has always pointed out that every marriage is cross-cultural.
It wasn't as hard for me as for my husband. My parents didn't care about race. His parents wanted their son to marry a Korean. Every time he went home to visit they set him up on a blind date, "You'll like her, she's studying medicine at Yale." They hadn't met me at that point so I didn't take it personally.
I dragged him home within four months of us starting to date. My parents were two of my best friends, so if they didn't like him, I knew it wasn't going to work. Of course they loved him (everyone who gets to know him loves him). During that visit my 92 year old grandfather was also visiting. I completely horrified Jrex as I verbally sparred with Grandpa. In Korean culture you treat the elderly with complete deference and here I was treating him as a peer. Of course, Grandpa loved it. I had that kind of relationship with both my grandfather, my Dad and now with my husband. Ironically, how I treated Jrex totally threatened my Dad at first. See, Dad married an amazing woman who did NOT understand sarcasm. At. all. So, despite the fact that I quipped right back at Dad, he couldn't handle me quipping at my husband. A wife doesn't DO that! He's since adjusted.
One of the many tragic aspects of my mom dying 6 months into our wedding was that she LOVED Jrex. She was his biggest fan. She never let me complain about him. Sure she could whine about my Dad to me, but if I even tried to do the same she'd jump all over me in Jrex's defense. The building is burning, who do you save? I think she would have grabbed him first! ;-)
We dated two years before I finally met his parents. His parents came up to Rochester for a weekend. We met them at the hotel. The whole drive there I nervously practiced "On yong ha sey yo" over and over. At dinner his mother gave me some lovely porcelin vases. I gave them nothing. Because. No. One. Told. Me. About. Koreans. and. Gifts. No one apologized profusely as he drove me home. He'd forgotten about gift giving! I learned then that I'd study Korean culture on my own since I couldn't assume I had a cultural guide at my side...
As much as we both communicate well and analyze everything, there were aspects of how he was that I thought were just him. It wasn't until we attended a 2nd generation Korean church in Baltimore that I realized how many things were elements of Korean culture. I receive love most effectively through verbal affirmation (thus the addiction to comments on the blog...). He never thought to compliment me. I found out, that's just Korean. In fact, if he were being culturally correct, he would insult me whenever someone else complimented me. Maybe that's just a parent's job, not a spouse's, but all my Korean friends have examples of how their parents "kept them humble".
For the most part, our core values are very similar. We value family and quality time. We believe in saving money but also buying good tools ("tools" being a tent, or a cool new waterproof messenger bag made of recycled bike tires). As Jrex told his parents before they met me, "You're idealizing a Korean woman and have horrible assumptions about American women. She's more Korean than most of the second generation Korean women I know."
The biggest asset we've had, aside from our friendship and mutual respect, has been two sets of parents who (in the end) were willing to bend toward each other's culture and try to understand and accomodate the other side.
