It is good to stay positive. I too am living with a roommate and have just been accused of eating his food when I went and bought and prepared the meal for myself. I try to let things that bother me pass by and focus on better aspects of my life. Unfortunately for me at this time it is a little harder to do so. His girlfriend lives with us rent free and seems to have taken over the entire space leaving me with mainly just my room. I have always tended to keep to myself and well moving to this new city has kind of thrown me out of whack in a sense and over the past two years I battled a fairly serious depression. While my current situation is upsetting I am learning a lot about myself and growing even if it is slowly. It really bothers me that things would break down to this point, but it seems that as soon as the lease is up I will be finding a new place to live. I will not think about it to much at this time and just try to stay happy.
