I never thought a simple ‘yes’ would upend my marriage, my sanity, and my sense of home. Opening our doors to my husband’s cousin Victoria, so she could attend college, seemed selfless at first—but as weeks turned to months, the boundaries blurred, resentments grew, and I began to wonder whose life I was living. Now, every day feels like a test of loyalty: to my marriage, to myself, and to the thin line dividing family from intrusion.
