AITA for putting a lock on my bedroom door in the apartment I share with my husband and his family member? Sorry it’s long.

In a home shared with family and their ever-present friends, a woman finds her sanctuary slowly eroding. The walls meant to protect her privacy feel thinner by the day, as uninvited guests cross boundaries without hesitation, leaving her anxious and vulnerable in a space that should be safe.

Her small acts of securing a lock and installing a camera are silent cries for respect and security, yet even these measures are violated. The intrusion into her private world by those closest to her fractures the trust she once held, turning her home into a battleground of unspoken tensions and unrelenting discomfort.

As renowned researcher Dr. Brené Brown explains, “Boundaries are the distance at which I can love you and me simultaneously.” This statement directly addresses the OP’s situation, highlighting that the need for personal space and security (setting a boundary) is not inherently an act of distrust or rejection, but a necessary component of maintaining both individual well-being and healthy relationships.

The OP’s initial action—installing a camera in the vanity room—and subsequent installation of a lock on the bedroom door stemmed from clear triggers: frequent unauthorized access by guests (L) and a general lack of security due to an unlocked apartment. These actions are reasonable responses to perceived threats to personal property and privacy, especially when living in close quarters with frequent visitors who do not respect private areas. G’s reaction, labeling the OP and their husband as “paranoid” and invoking familial “trust,” functions as an emotional maneuver to dismiss legitimate needs for security and autonomy. This pattern suggests G may be struggling to differentiate between familial obligation and the necessity of respecting established personal boundaries within a shared domestic setup.

The OP’s actions in securing their bedroom were appropriate given the preceding invasion of the vanity room and the constant traffic. A constructive recommendation for future interactions involves framing privacy not as suspicion, but as a structural necessity for cohabitation. The OP and their husband should communicate clearly and calmly with G, perhaps suggesting neutral ground rules for guest access to personal rooms, reinforcing that these measures protect everyone’s peace, rather than targeting G or L specifically.

The original poster (OP) is experiencing significant emotional distress, feeling like an outsider in their shared living space due to a lack of personal boundaries. The central conflict arises from the OP’s attempt to secure basic privacy by installing locks on personal rooms, which conflicts directly with the sibling’s (G’s) expectation that family members operate solely on unconditional trust without personal boundaries.

Given the breakdown in trust and communication, the core question remains: Is the OP justified in prioritizing their established need for privacy and security by installing locks on their personal spaces, or did this action fundamentally violate the expected trust within a family living arrangement, making them responsible for the current hostility?
