AITA for switching to regular milk to prove my lactose intolerant roommate keeps stealing from me?

In the quiet confines of a shared apartment, trust is meant to be the unspoken bond that holds everything together.

But when som**hing as simple as a container of food becomes a battleground, the walls start closing in, turning everyday life into a silent war of accusations and broken respect.

For one tenant, the invasion of personal boundaries by a roommate's constant theft fractures the fragile harmony they once shared. Every missing bite, every emptied carton of almond milk, carries the weight of betrayal and frustration.

Despite confronting the culprit, denial and gaslighting only deepen the wounds, leaving one roommate isolated in his truth, while the other remains steadfast in innocence.

The tension is not just about food—it’s about dignity, respect, and the invisible line crossed too many times.

Strong Takes and Sharper Words from the Crowd:

It didn’t take long before the comment section turned into a battleground of strong opinions and even stronger emotions.

The original poster (OP) experienced persistent theft of personal groceries by a roommate (R), which escalated after repeated denials and gaslighting from R.

The conflict climaxed when the OP set a trap using lactose-containing milk, successfully exposing R's dishonesty, though R reacted more strongly to the trap than to the initial act of theft.

Given the clear v***ation of agreed-upon boundaries and the subsequent denial, was the OP justified in setting a trap to expose the repeated food theft, or did this action create an unnecessarily hostile living environment?"
