“Physical proximity is extremely important and necessary for attachment, but it is not sufficient if the quality of presence is poor. Being present with your partner is important for people in any relationship structure, but struggling with presence and availability is a common complaint in nonmonogamous relationships since there are typically more people to attend to in any given day or week. One of the most common complaints that I hear is of situations where partners are spending quality time together and one partner is messaging with other people in ways that feel distracting and interruptive.”
