Cowboy / Cowgirl

The cowboy or cowgirl pattern is notable because it can occur through malice or through genuine misunderstanding. Someone who consciously sets out to win a polyamorous person away from their other relationships by pressuring, manipulating, or creating ultimatums is doing something recognizable as harmful. But the pattern also appears in people who genuinely like the person they've met, find themselves developing stronger feelings than they expected, and begin to push for more exclusivity without fully acknowledging to themselves or the other person that this is what they want.

The phrase is used most often as a warning label in polyamorous communities — something to watch for in new partners, a pattern to recognize early. The behaviors that tend to signal it include escalating pressure for more time and exclusivity, subtle or not-so-subtle criticism of the other partners, framing the non-monogamous structure as a phase to be grown out of, and expressing discomfort with the polyamorous identity itself rather than just with specific agreements.

The term is gendered in a way worth noting. The cowboy and cowgirl terms originated with different gender assumptions about who does the roping, and those assumptions have mostly dissolved in contemporary usage — both terms are applied regardless of the genders involved. Some communities have shifted toward gender-neutral alternatives, but the original terms remain widely recognized.

Not everyone who struggles with a partner's other relationships is a cowboy or cowgirl. The pattern specifically involves an attempt to change the relationship's structure toward exclusivity. Someone who is honest about their monogamous preferences from the beginning and discovers they can't genuinely embrace polyamory is not a cowboy — they're a person whose needs and their partner's needs may simply be incompatible, a different and more sympathetic situation.
