<human>: I live in Massachusetts in the finished basement of a married couples house. It's a studio apartment with a shared washer/dryer in the bathroom. There is a separate entrance to this laundry/bathroom so she's got no reason to come into my room.    

My "landlord" technically is the wife of the couple because it's her family's house. I work two jobs and am only really home on the weekends and at night to sleep. My landlord is in my room doing god knows what every single day and the only reason I know this is that things in my room are moved around by the time I get home. My clothes will be in a pile in the corner instead of on the floor, she'll text me and tell me I need to do dishes, etc. Her being in my room while I'm not makes me uncomfortable and if I'm paying rent to her I think I should be allowed my privacy. I can't lock the door because she's got a copy of the key. Am I wrong feeling this way and is she breaking any laws?

Can you give me the gist of the text in a nutshell?
<bot>: my landlord invades my room while I'm at work nearly every day, what can I do to protect myself and my things
