Then invite an adult conversation. Ask what a car represents to him—freedom, status, relief from stress—and lay out the real costs and your actual financial limits.If transportation is a genuine need, explore shared solutions: a used car, cost-splitting, saving together, or alternative options. If he chooses to move out, let it be his adult decision, not your guilt. Help him see the full budget of independence, then step back. Your job now is not to rescue him from every discomfort, but to stay connected while he learns that maturity isn’t given with a set of keys—it’s earned through choices, consequences, and respect on both sides.
