Indicators of brief or long term (marriage) in a composite chart??

What are they?

What can signify a brief relationship or one that is probably going to end in marriage in a composite or synastry chart?

it is too complex to isolate a aspect or two.

but in general uranus in a hard aspect to venus or jupiter will be brief.

stabilty is complex but with a pattern with sextile and trines including sun/venus/moon/jupiter, shows a relationship that has a good chance of turning into a marriage.again keep in mind that this is over simplified.
