Those couples who can rely on each other are the ones to have the most successful lasting relationships, states to a new study.
Scientists at the Edinburgh University found that what people think they desire in a partner is often unrelated to what they end up choosing.
"The most likely romantic partners are those that are around you every day at times when you are looking for a match," the Daily Express quoted relationship specialist Dr Lars Penke as saying.
"Students, exactly at the age when most people look for romance, are fortunate enough that they are surrounded by many potential partners," he said.
The findings of the study were published in the European Journal of Personality.
