What do you make of this situation?

When my boyfriend and I met, I had lived alone for 13 years. He had been sharing a cramped two-bedroom flat with his sister, her boyfriend, and a friend—sleeping on the sofa. I told him I didn’t want to stay over there because it felt like student housing. Instead, he stayed with me from Thursdays to Sundays.

After we had our child, he started a remote job and asked me to stay at his place while he completed probation, as he needed to be tied to that address. He reassured me his sister and her boyfriend would support us if needed and that they were responsible adults.

Before moving in, I made it clear I would only clean up after myself, our child, and our dog. I was friendly—greeted them, made small talk in the evenings—but over time, they grew distant. They often ignored me or stayed in their room. Once, when I knocked to ask for something, the smell from their room was awful. I told my boyfriend it made me uncomfortable and suggested we talk to them. He opted to text instead, which led to sporadic greetings and mostly being ignored.

I grew frustrated—they didn’t clean up after themselves in shared spaces like the kitchen and bathroom. I also noticed they were taking financial advantage of my boyfriend: not paying rent, relying on him for groceries, and wasting food. He would complain to me but never confronted them. When he did ask for help with chores, they’d leave it for days. He’d excuse it by saying, “Well, I didn’t give them a time.”

We started arguing more, especially when the mess prevented me from cooking dinner. I felt isolated and depressed, and eventually told him I wanted to return to my flat. That conversation escalated, and he became violent. We’re now separated, and the matter is with the police.

I keep wondering—was I out of line for speaking up?
