When you don’t talk to someone for a while, it feels like you’re fine without them, and, until you are reunited, you don’t really feel the necessary to reach out.
This feeling is often called emotional detachment or emotional self-sufficiency. It’s also related to things like low-maintenance relationships or dormant intimacy, where you feel secure in a connection even if you’re not always in touch.
It could also just reflect traits like independence or introversion.
For people who feel drained or overstimulated by social interactions, it can create a sense of emotional detachment or a desire for more space. If you're someone who experiences social exhaustion or has low energy, you may naturally feel more comfortable with emotional self-sufficiency and less frequent communication.
