Questão jurídica principal
Whether the husband's duty to pay spousal maintenance had to be suspended during the wife's simple concubinage.
Decisão extraída
A mere simple concubinage did not justify suspension on the facts shown; maintenance was only limited until 2021, when a qualified concubinage would be presumed.
Fundamentação extraída
A suspension requires specific circumstances; the husband did not demonstrate them. The risks of a change in circumstances are unequally distributed, since the wife could later seek an increase only in exceptional cases.
