What are the exact circumstances that qualify as rape? Is the self-report measure reliable?  Emotional manipulation as a mate retention behavior: showing care and affection  The greater amount of time spent away from a partner, the greater the probability of sexual jealousy  Observers were more accepting of violent behavior when it was clear that sexual jealousy was triggered  We question the correlation between sexual jealousy and violence.
