Another reason not to marry.
Seems like even unmarried, but cohabitated, the relationship would fit the mold wherein the incomes of both “participants” in the relationship ought legally (or pursuant to federal regulation) to be combined, so as to establish a final figure for reporting on the FAFSA forms as “household income”.
Meaning, the only way for the relationship to NOT produce higher household income is for there to not also be cohabitation.
