Am I alone?

I wonder what's going on at my apartment...
Yesterday, when I came home I felt a little uneasy. Something was not like it used to be. The floor was too clean and the hall too empty. The usual trash near the front door was gone and the clothes rack in the hall had only a few coats on it as opposed to it's usual abundance of clothes. There were also just a few pairs of shoes. The kitchen was like it always is, filled with old food and unwashed dishes and generally a mess. Seeing that put me at ease, and I went to my room and closed the door like always. I thought my host might have got the splendid idea to clean up some of the family's clothes, possibly to sell it or something... She was not in, but I didn't think too much about that. Although she is usually here, she does sometimes leave the apartment.
Today, I am increasingly worried. It's not a natural thing for me to be worried, but being abroad simple things can sometimes be a little more scary. The apartment today is almost completely empty. I don't know if the living room was this empty yesterday, I didn't check, but today the door was open and I could see that all the furniture was gone. My host is still nowhere to be seen. The kitchen looks exactly like yesterday, except there's now mold on some of the food (please, don't think badly of me for not cleaning it; doing so would be a massive task and I don't think my host would be grateful for it). How do I eat? You might wonder. There's a microwave and the ready-made steam-cooking meals from Albert Hein (convenience supermarket) are of high quality.
This is a strange post I know, but please don't be worried for me. I will worry myself, so you don't have to. I've got several back up plans in mind if my host decides to move out of her apartment without telling me. I'm preparing for the worst, but I hope she will come back soon and explain what's going on.
