I am not going delve very deep into this because it is not an area of my expertise but the little I know is how complex this issue is.

Domestic Abuse Statistics

That is specifically psychological aggression but the "one in three women" part links to another site that states that 36% of women vs 28% of men have experienced physical violence and stalking from an intimate partner. But that statistic is already more complex because much violence happens in self defense and a lot of violence from intimate partners is conflated with violence by family members.

12 child custody statistics

That's because fathers are less likely to sue for custody. And there are many special cases where father's are more likely to get custody.
