<p>Technology has transformed romantic communication, allowing partners to remain connected through face-to-face interaction, text messaging, social media, phone calls, and video calls. At the same time, situationships (romantic relationships marked by ambiguity and an absence of clear labels or commitment) have become increasingly prevalent. The present study examined whether communication frequency across modalities predicted trust in romantic relationships and whether these associations varied by situationship status. Data were drawn from 261 emerging adults who reported on their last three romantic relationship experiences, 34.1% of which involved a situationship. Multilevel modeling analyses showed that communication frequency was positively associated with trust across most modalities, though these associations were often non-linear. Situationship status was a reliable main-effect predictor of lower trust in the partner and lower perceived partner trust across several communication contexts. In contrast, interaction effects between communication frequency and situationship status were largely nonsignificant, indicating that communication operated similarly across situationship and non-situationship relationships. One notable exception emerged for perceived partner trust: at a high level of texting frequency, situationships were associated with relatively higher perceived partner trust, suggesting that frequent texting may serve a compensatory function in more ambiguous romantic relationships</p>
