Violence against a live in female marriage partner.

Lesbian couples are more likely to have domestic violence however given there’s so few lesbian married couples obviously the sheer number of domestic violence incidents are very low compared to hetero numbers. But percentage wise lesbian married couple relationships are more likely to feature abuse.

I had read that this data is often misinterpreted out of context. The original studies were that more lesbians reported being victims of DV, but that included incidences of DV in prior relationships with males. Anecdotally I see considerable support for that.
