micro-cheating

/ˈmaɪkroʊ ˈtʃiːtɪŋ/

Common

Small, repeated behaviors that cross the line in a relationship without being full-on cheating.

What counts as micro-cheating is almost entirely relationship-specific. One couple's normal friendliness is another couple's dealbreaker. The term is sometimes criticized for setting impossibly restrictive standards.
