BarrenPneuma: There may or may not be a singular soulmate out there for each and every person, but there is in truth no requirement for such. Commitment and determination to press through whatever issues arise that must me met head on equally by both parties is absolutely required to maintain this illustrious position.
Absolutes scare me; but, I'll get to that later.(or perhaps not

) Altruism is noble and profound; because it sounds really good, like the knight on a white horse rescuing the maiden; but its largely impractcal in RL use.

Monogamy is not the cause of failure in marriage, it is rather the pressing individual needs that is nurtured by our media that is crippling our ability to persevere against obstacles as more than a singular entity. A failure to maintain a connection to the spiritual and thus allowing us to lose our focus. We are all about the here and now and how that affects us as if there is nothing else. The loss of spiritual goals has made the concept of unity fade to a bitter dream for many and an impossibility for more.
Aren't we all trying to maintian? whether its spiritual or physical or verbal? Focus seems to have its own way with people as well and perhaps this is relative to one's self, moreso than than any outside vision of togetherness, including monogamy for whatever its benefits are.
In response to:
If our mate is less in some way should we not seek to bolster those points as they would do for us? Rather than abandon them to seek something that will make us 'better?'
To what extent? Just how much is too much reason to remain and bolster another? In the end, bettering ourselves comes from within, not from the expectations of others, no matter how hurt we are because of their abandoning us. Being dramatic about abandonment doesn't alter that fact. In fact it only creates victimisation, which is the very
self oriented desire you denounce in the absolutes of altruism?
In response to:
Most marriages fail because of selfish impositions. When marriage is intended to be a selfless prospect that supports two individuals in a union of one.
And if neither has 'impositions' of any sort, what then? Stale relationship or stalemate?
I think you've neglected the art of negotiation; but that is off OP.
