I can feel your frustration. I wonder if the landlady just knows that you're kind of stuck, so she can treat you poorly if she wants to. She knows you'd be hard pressed to move, so she takes you for granted. It's a horrible situation all the way around.
Not to be rude, but how comes your partner doesn't help pay the bills? Or does he? Sorry, it's just the obvious question.
Does Canada not have something like Food Stamps in the states, that covers your groceries?
We just have the most basic internet, and we get a government credit that makes it $25. We have a roku for the TV, so no cable bill, and I just pay for Shudder. Don watches loads of really old shows with commercials. I pay for streaming services only when there's something I specifically want to see. Like Shudder for Joe Bob.
I don't understand the animosity in some comments. You have nothing but my sympathy. We lived in a van once for six months. I know how shitty things can get when you're poor.
