Maturity is choosing systems over habits, inspiration over motivation, discipline over emotional decision-making, boundaries over feelings, pausing over reacting, peace over being right, agreements over expectations, and discernment over comfort zone. That's growth, not coldness.
An adult relationship that requires you to do their emotional work is unsustainable and not worth keeping. It's not your job to manage their emotions and pacify their chaos. Love alone isn't enough to sustain a dynamic where only one person is committed to emotional maturity.
