Texas Tech University found that although the stages of coping with online infidelity are unique, the infidelity itself creates similar emotional experiences for the partner who was cheated on.
"This is very important because there is a line of thought that if the infidelity was discovered online, or confined to online activity, then it shouldn't be as painful," said Jaclyn Cravens, a doctoral candidate in the Marriage & Family Therapy Program and lead author of the study.
"We used Facebookcheating.Com to determine the coping process for people who have discovered a partner's infidelity on Facebook," Cravens said.
"We discovered several main themes and were able to create a process model that moves through different stages of the ways people deal with the information," she said.

The model includes five stages. First, there are warning signs: the partner who was cheated on notices gut feelings and/or suspicious behaviour on the internet, such as minimising windows, habitually clearing out browser history and adding passwords.
The third stage is damage appraisal where the individual determines whether the discovered acts was or was not a violation of the relationship.
If the individual determines that the act or acts were a violation of the relationship, he or she either confronts or avoids the partner. Sometimes the individual decides that the evidence wasn't concrete enough to be able to approach partner.
Others retaliate, which typically includes posting messages online or sending a message to the third party, or the third party's partner. The last stage includes making a relationship decision.
Regardless, she said the emotional impact for the party who has discovered online acts of infidelity is no less severe than acts committed in-person.
"People have ability to be more vulnerable online, which facilitates a greater emotional response. This can be just as devastating if not more devastating than an offline response," she said.
