For seven years, a sister and brother-in-law shared a marriage once filled with warmth and joy. But over the last four years, his descent into heavy drinking transformed him into someone unrecognizable—belligerent, destructive, and a source of constant fear and pain for those around him.
When they visited recently, the fragile boundaries of their family’s safety were shattered once more, as careless actions fueled by addiction led to a terrifying explosion. The incident was a stark reminder of how deeply the darkness of his alcoholism had taken hold, threatening to destroy not just property, but the fragile bonds of love and trust.
AITA for telling my sister she could only stay at my house if my brother in law controlled his drinking.
As renowned researcher Dr. Brené Brown explains, “Boundaries are the distance at which I can love you and me simultaneously.”
The situation highlights a severe breakdown in relational boundaries driven by a third party’s substance abuse. The OP acted reasonably by attempting to manage risks (preventing a child from accessing hazardous materials and stopping property destruction) after previous incidents occurred under the brother-in-law’s intoxication. The OP’s initial polite requests were ignored, leading to escalation and significant material damage. When the OP finally placed a clear condition on future hospitality—control over drinking—the sister and brother-in-law reacted defensively, framing the boundary as an attack or an imposition. This reaction suggests a lack of accountability on the part of the in-laws regarding the severity of the past incidents (the discarded bottles and the fire damage). The emotional labor of hosting someone whose behavior necessitates strict pre-conditions is high, and the OP is justified in prioritizing the safety of their home and child.
The OP’s action was appropriate given the documented history of destruction directly linked to the brother-in-law’s intoxication. A constructive path forward involves shifting the relationship from one based on conditional tolerance to one based on clear behavioral prerequisites for access to their home. If the brother-in-law chooses to drink heavily, he must accept that he forfeits the privilege of staying at the OP’s residence until he demonstrates consistent behavioral change and agrees to cover the costs of previous damages.

The original poster (OP) is clearly struggling with setting firm boundaries to protect their property and child from the destructive behavior associated with their brother-in-law’s nightly heavy drinking. Their attempts to enforce simple rules, like managing trash or preventing property damage, resulted in conflict and accusations of being unreasonable.
Was the OP wrong to request that their brother-in-law control his drinking and refrain from causing further damage to their home before allowing him to stay over? Or were the sister and brother-in-law justified in feeling their autonomy was infringed upon by such a condition?
