<human>: Our apartment was 'broken into' yesterday while we were at work. Valuables amounting to thousands of dollars were taken - mostly cash in different currencies and the engagement ring that my boyfriend was going to give me. 

We've called the police and cancelled credit cards that were left in the house. Because of lack of point of entry (we're basically snowed in, no broken windows and lack), police think it's an inside job. Our apartment did not look tampered with at all. The ring was in a box, which was in a bag, which was in a box, which was in a fedex envelope and only the ring is missing. We had to open up all the layers to find the ring missing. The police took the boxes, bags and envelopes to get fingerprints. The thief obviously spent a lot of time going through our stuff because things were placed back to where they approximately were, but not exactly. In fact, I only realized that things were not right because my makeup brushes were in the wrong order, and my boyfriend swears he did not touch anything. We then search for all our cash (hidden in various parts of the house) and they were all gone.

Meanwhile, we don't have renter's insurance and the ring was uninsured too (it's only been with us for less than two days.) What should we do next?

I feel violated and unsafe in my house, but feel the need to stay here in case they decide to return.
