Americans may be growing more cynical when it comes to politics, the state of the economy and perhaps the world in general, but that hasn’t stopped them from believing in the one thing more fickle than them all: LOVE.

According to a new national report “The Happiness Index: Love and Relationships in America” by eharmony, 64 percent of Americans are “very happy” in their romantic relationships with a partner or spouse and nearly 50 percent report being happy with their sex lives.

“At eharmony, we talk a lot about happiness in relationships and how to keep them going strong,” says Grant Langston, chief executive officer for eharmony. “We wanted to put society to the test and get a sense of how couples are living and loving in America today. Perhaps the most surprising finding is that gender and age dynamics in relationships are evolving, debunking misconceptions long held about both men and millennials.”

The new survey reveals that millennials ages 25 to 34 are the happiest in their relationships. Presenting a counter-narrative to the belief that divorce is rampant, 19 percent of Americans report being unhappy in their relationships, but say they are finding it worthwhile to stay together for the long haul: the average length of a relationship is 18 years overall, spiking up to 36 years for respondents over the age 65.

In addition, the survey identified the secrets to success for the 26 percent of respondents who said they were “perfectly happy” in their long-term romantic relationships. Perhaps unsurprisingly, they tended to have taken the time to get to know one another before taking the plunge into marriage, were the same age as their partner or spouse, and had many shared interests, making time for each other even after having children.

(On the flipside, only six percent of respondents characterized themselves as “desperately unhappy” in their relationships, and were likely to have prioritized companionship over love, lacked intimacy and were less likely than average to be married.)

Here’s how this data can help guide us during the online dating process.

1. Find someone with shared values and a similar approach to conflict resolution.

According to the study, people in the happiest relationships share similar values, like ambition, confidence, optimism and are people who handle conflict resolution the same way. It makes sense, if you have different values and an opposite approach to resolving conflict (i.e. one of you likes to talk about everything, whereas the other person prefers to avoid conflict altogether, allowing it to mushroom cloud at a later point) you’re going to have a much more difficult time getting along.

2. Compromise is important.

Millennials are leading the way when it comes to working through their problems. According to the data, young people are the most positive about handling relationship difficulties, are twice as likely to have tried counseling or therapy and are more open to compromise, demonstrating maturity and conflict resolution. Regardless of whether you’re a millennial, look for someone who is open to talking about their issues, working through them and compromising. A relationship is a give-and-take. You can’t expect to be happy if you both insist on a “my way or the highway” approach.

3. Money matters.

Unfortunately, money does matter in certain cases when it comes to love. Those with the highest household income report the highest level of both happiness and satisfaction with their relationships. Seventy-one percent of people with a household income of more than $200,000 say they are completely in love, yet those making less than $30,000 a year come in second at 65 percent. This makes a lot of sense considering 27 percent of people report arguments about money (more money = less arguments about money.)

With that said, while the survey results show a correlation between income and happiness in relationships, money can’t buy love. Nearly three-quarters of Americans still report having a warm and comfortable relationship, with minimal variances across household income. So, perhaps the key isn’t a high income, but finding a partner a partner that has a similar approach to dealing with conflict (as mentioned above).

4. Men are romantic.

Romance isn’t dead! While women tend to show more signs of daily affection, such as saying “I love you,” men are bringing the romance. In fact, they are much more likely to hold hands with their partner, share an intimate kiss, write a love note, take their partner out on date night and even buy small gifts, just because. So, if romance is what you crave and your date says they’re “just not very romantic” – don’t feel like you have to settle.
