Forgot to say landlord already said me sending just my part of the rent from now on was fine, after last month. I'd already told her I wasn't comfortable with the arrangement putting all the responsibility on me. Lease is supposed to go through end of May of next year, however the end of the lease has a paragraph about "intention to vacate" and says I need to give 45 days notice, hence me paying for September and potentially them keeping my deposit for the rest. I'm not sure if that would even apply though because roomie would still be living there, and I'm pretty sure he'd just have one of his buddies move in. But my understanding is that, either way, after 45 days it is no longer my problem. Of course landlord is in Canada until either the 3rd or the 4th so I can't call her until then.
