We Could Reasonably Predict That in the Immediate Future the Divorce

We could reasonably predict that in the immediate future the divorce rate for same sex-couples in Canada will be lower than for heterosexual couples because

A) same-sex couples are not legally permitted to get married.
B) a good proportion of same-sex marriages involve couples who have been in long term relationships.
C) same-sex couples prefer cohabitation before marriage which means that when they dissolve their relationship, it will not count as a statistical divorce.
D) there are far fewer same-sex marriages in Canada and so a comparison to heterosexual marriages is not possible.
E) same-sex couples are much more committed to their marriage than is currently the case for heterosexual couples.
