the definition of marriage is it is for life.

if you can divorce a woman that isn't marriage.

as for abusing the woman - most women would rather be abused by a high value man than loved by a low value man. 

 If you groom a girl when she is very young, she would be attached to you that she would stay with you and not leave for someone better.  

 that's why Jews cannot allow this.

this is why they invented Feminism as well.

to make sure whites can't form stable families and produce lots of offspring.
