Though the evidence is small, here in the UK the highest rates occur in lesbian relationships. The current theory is that this is because males are presumed to have a tendency to violence and therefore a lot of effort is put into socializing males into controlling their emotions and impulses. The presumption being that the male in a heterosexual relationship or both in a "gay" relationship will have skills in managing aggression and anger that are absent in lesbian relationships. Sounds plausible.
