3. They crave the initial excitement and illicitness of a "secret" affair.
4. They need to feel desired and their partner may not fulfill that need.
5. Some think they can get by with it.
6. Some stray outside of long-term relationships to remember what it was like to be desirable and free. "Schedules" and routine destroy self image.
7. Having more than one relationship is an ego boost for those with low self-esteem.
8. Maybe because they are bored in their current relationships
9. Lack of or poor communication with the girlfriend.
10. There's no old baggage with someone new or maybe they want something with ''no strings''
