5th function and relationships.
Maybe this has something to do with why relations of activity are popular in relationships? (I got the idea from INFp profile that says they may marry for money.)
It seems we might be more aware that we like "help" in the 5th function.
= Marry for money and will power.
= Marry for looks and pleasure.
= Marry for knowlege and practicality.
= Marry for depth of thought and insight into things.
= Marry for enthusiasm and happiness.
= Marry for moral support and human insight.
= Marry for insight and awareness of opportunity.
= Marry for foresight and spirituality.
