What Science Says
Although it may be easier to approach someone with the same background as you, because it gives you immediate things in common to talk about, a similar background is not actually what most people want in a relationship.
A study published in the “Journal of Social and Personal Relationships” in 2002 showed that people rated warmth, openness, humorousness, attractiveness and intelligence as more important than background when considering a long-term relationship. Focus on the lovely qualities a person has, rather than where he or she comes from.
Although background might not be as important as personality traits, research has shown that external factors do play in role in whether people stay together or not.
According to a study carried out by sociologists at the University of Wisconsin-Eau Claire, college students reported that they were more likely to leave their current relationship in the near future if they began to share less similar values or did fewer leisure activities together. Spending quality time with your boyfriend or girlfriend can ensure you don’t grow apart.
The same research, titled “Influences on College Relationships: Staying Together or Breaking Up?” showed that culture and family background might play a part in whether guys and girls stayed together.
