It seems that betrayal really is in the eye of the beholder.
A recent HuffPost/YouGov survey of 1,000 U.S. adults found that people's definition of emotional infidelity depends on who's doing the cheating.
Sixty percent of respondents said that if their partner developed a deep emotional connection with someone else, it would be considered cheating. Only 18 percent said that it wouldn't be considered cheating.
However, when a separate group of 1,000 adults was asked the reverse -- "Say that you were in a committed relationship and you developed a deep emotional connection with someone other than your partner. Would you consider that to be cheating?" -- the number who said "no" increased to 29 percent of respondents. Fifty percent said "yes," and 21 percent were not sure.
Much of that change came among women, 70 percent of whom said developing a deep emotional connection would be cheating if their partner did it, but only 56 percent of whom thought it would be if they did it themselves. Men were more consistent -- 50 percent said developing a deep emotional connection would be cheating if their partner did it and 44 percent said it would be if they did it themselves.

The HuffPost/YouGov poll was conducted March 8-10 among 2,000 U.S. adults, 1,000 of whom were randomly assigned to answer each of the two sets of questions. The poll used a sample selected from YouGov's opt-in online panel to match the demographics and other characteristics of the adult U.S. population. Factors considered include age, race, gender, education, employment, income, marital status, number of children, voter registration, time and location of Internet access, interest in politics, religion and church attendance.
