Combining Two Cultures in One House?

Okay, this isn't about a wedding, but it is about what comes next. My fiance and I are both older 40 and 50, and we both have our own house. My house is small, one bedroom, and his is 3 bedrooms, two bathrooms. I will be moving into his house as soon as we are married in December. My family has been in the US since the 1700s, and for most of that time, we have lived in Mississippi. So I am truly a southern girl, with my house decorated in an eclectic combination of country, folk art, and a bit of 'cottage-look.' I have a few family antiques, cross stitch and prints with Amish scenes. My fiance's parents immigrated from China when they were children. He lived with and took care of his ailing mother until her death, and that is the house he lives in. His house is filled with china, pictures, and figurines, etc from China which are primarily red and black. Has anyone else had to combine two such different cultures and styles? I would love to chat with you and find out how….
Please don't think I am complaining. I am not. I want for the house to express both of us, but it is going ot be a challenge. Want to know how it worked out for other people. Thanks!!
