Roommate gave notice to end lease without telling me

Sorry it’s going to be a long story. My roommate and I shared a 2 bedroom apartment unit for almost 2 years now. We signed the lease together for a year, and after that, it was a month to month basis. Before signing the lease, we were good friends, and we shared another place for few months before moving into this apartment.

For context, our relationship as roommates has been extremely strained since we moved. Before we even moved into the apartment, her boyfriend tried to make a move on me while she was drunk and asleep. I rejected him immediately and never told her about it because I didn’t want to come between them or create drama.

After we moved in, her boyfriend was basically living in the apartment all the time. Though I never saw him in the kitchen or in the living area, but I knew he was in her room, all the time. When I pointed that out, she got upset with me. Since then she kept her distance and was always cold toward me. I still tried to be friendly sometimes, by offering food or trying to talk, but she never really responded and eventually I stopped trying.

We only communicated when it was necessary, like about rent or bills.

At one point she didn’t pay her share of the Wi-Fi bill for about four months. I eventually changed the password and she had a huge argument with me about it that lasted almost an hour. She was yelling and saying I should have trusted her and told her first, but from my perspective she hadn’t paid or communicated anything for months.

After that argument we basically stopped talking entirely.

Living with her has also been frustrating in general. She rarely cleans, leaves dishes in the sink for weeks or months, and the shared bathroom is often left in a mess. I’ve cleaned up after her many times just to keep the place usable.

Now the main issue, I suddenly received a message from the building management about a move-out inspection. I thought it must be a mistake, so when the management staff came by I asked them about it. They told me that “we” had already submitted a two-month notice to terminate the lease.

The problem is I never agreed to that and never signed anything. Apparently my roommate submitted the notice without even telling me.

The landlord has asked me to come talk with them on Friday about the situation.

I’m honestly extremely frustrated because I’ve tried to be reasonable and respectful the entire time, and now I find out she may have tried to end the lease without my knowledge even though my name is also on it. I might sound rude now but help get back to her on this and I am done being nice to her.
