Commitment and even love are terminable in a way that obligation is not because both are subjective and can, to some degree, be chosen or unchosen. On the other hand, one may ignore an obligation, but cannot will it out of existence. An obligation is objective.
I think about this law review article constantly.
In a recent decision from New York’s appellate division, (which is not old) the court stated that: It is an undisputed fact that the vast majority of procreation still occurs as a result of sexual intercourse between a male and a female. In light of such a fact, “[t]he State could reasonably decide that by encouraging opposite-sex couples to marry, thereby assuming legal and financial obligations, the children born from such relationships will have better opportunities to be nurtured and raised by two parents within long-term, committed relationships, which society has traditionally viewed as advantageous for children.”65 The risk of a redefinition of marriage is that this social understanding and the goods it promotes are in danger of being lost in the new adultcentered version of marriage.We lost something really important, and there isn't a quick fix.
