Along with compliance with good form, as in formal relationships, doing the honorable thing and all that traditional dating/marriage stuff, it can also be acting on the Higher Plane. Go for a real relationship rather than anything else, seek someone for who they are, how you feel around each other, someone who gives you a sense of belonging, someone you fit right in with, perhaps someone with similar spiritual beliefs. Hierophant is of the earth, but is connected to the intellect and spirit... when the fizzle wears off, you want someone you are also best friends with to talk to and can stimulate each others minds and feel blessed.
