a marriage is about commitment first, followed by trust. the trust element is all about the commitment(til death). the problem with marriage is that breaching the commitment is built in - the lisence a prelitigation of the parameters of the divorce. a legal marriage almost guarantees a divorce. its part of the package. if you dont get a divorce, you have not availed yourself of all the options thereof. when a marriage does last, the formalities of it were never a factor in the first place.
