You don't make me feel like you used to. That's why I'm leaving That's why people leave each other They come to their senses and get selfish again.

The speaker frames a breakup as an emotional accounting: the relationship is judged by how it makes one feel, and when that feeling fades, departure is justified. The lines suggest a cycle in which people initially surrender self-interest—romantic “unreason” or idealization—then “come to their senses,” reclaiming personal needs and boundaries. Calling this return to selfhood “selfish” is deliberately bitter: it implies that love often depends on a temporary suspension of ego, and that separation is less a dramatic betrayal than a reassertion of individual priority. The quote’s sting lies in its cynicism about intimacy as a fluctuating state rather than a stable commitment.
