A new study has found that while most relationships can be a source of happiness, they are also hard to maintain.

Researchers at the University of Cambridge’s Department of Psychology and Social Policy found that in most relationships, it is difficult for a person to feel valued.

They compared the experiences of couples who have a good relationship with someone they know well, but have not met or had an intimate relationship, and those who have had no meaningful relationship.

The results, published in the journal Personality and Social Psychology Bulletin, show that the two groups tend to be more similar in their level of happiness and overall happiness.

However, they also found that they were less likely to have had a meaningful relationship than those who had a relationship with a stranger.

The researchers asked participants to complete surveys about their happiness, life satisfaction, and their relationship satisfaction, while also assessing their relationship’s overall level of satisfaction.

They found that the good relationship group, which had experienced at least a three-year relationship, was more satisfied with their life and the overall quality of their relationship.

They also found the relationships in the bad relationship group were significantly less satisfied, with fewer than one-third of participants reporting that their relationship was a source or an important factor of their overall well-being.

They concluded:”The study shows that while it is important to build strong friendships, a good, meaningful relationship may be more difficult to sustain than a long-term friendship.

These findings may help to inform the research to develop better tools for assessing the long–term well-beings of couples in relationships.”
