Researchers asked 1,000 of its male and female members why and how they would dump a partner.
Going against the stereotype of the commitment-phobe male, the most popular line used by women in ending a relationship is: "I'm not ready for commitment yet".
The second most popular reason is: "This is going too fast for me", the 'Daily Mail' reported.
"You don't earn enough money" is the third most important reason on the women's list, whereas it doesn't feature at all on the men's list.
The third most popular reason for men is they are no longer attracted to their partner and the fourth most popular reason is: "We've lost that sexual spark".
Both sexes prefer to end a relationship face-to-face but they are also increasingly using email and text to tell a lover they are history, the report said.
