I just moved out while he was working and left a note
Are you sure that this was the right choice?
Yes, I was very confident about my decision.
Moving out was fine and probably the correct choice for you but not giving your roommate notice was extremely rude and disrespectful. You just left them with the responsibility to pay rent alone and no warning that they would need to do so. How would you feel if they did that to you?
It's fine. No one will care or take notice since the roommate was even more messy and acted like a slob.
Your roommate will most likely be very upset to find out that you moved out. Your roommate needs someone to pay the other side of the rent, and you giving them no notice is going to put them in a hole. In addition to that, it just seems pretty mean in general to leave someone who may have been a friend without any word.
