Letting Hasan go may be reasonable when a relationship repeatedly undermines your wellbeing, boundaries have failed, and separation would be safer or more honest than staying. It is usually a mistake when the impulse is reactive, when important conversations or support plans have not happened, or when legal, financial, or caregiving consequences are unaddressed. Before deciding, clarify the core problem, consider professional guidance if stakes are high, and weigh alternatives such as boundaries, counseling, or a structured break. The right path depends on context rather than a universal rule.
