I hope your landlord is nice about it and lets you two stay, at the very least until you find somewhere else, and lets you off without damaging your credit since it wasn't your fault the lease was voided. Are you sure your former housemate intended to steal from you? Maybe she thought those items were hers. Still, it's perfectly legitimate and safer to just change the locks. There is no reason she should need access to the house without your permission as long as she is not living there.

My significant other and I recently signed a lease to a one-bedroom apartment for next school year, and we're so glad to not have to deal with housemate drama anymore. Not that there was ever a lot of that. Mostly just me fuming about certain people who frequently left disgusting dirty dishes lying around the living room, dining room, and kitchen. x_x
