This person has mild mental issues, it's not severe, but I think they have some kind of paranoid personality disorder, they went to work for around 7 months or so and then started imagining people at the work were sabotaging them at work and even eavesdropping the house
I think they are looking for a job now... I didn't mind them being that unstable to be honest, I just didn't know they would be dishonest. They have some kind of mental problems where they are like a child, they never lived on their own or supported themselves (26 years of age btw).
They have the mentality of a child, for example last time we got in a fight they emptied 3 HUGE bags of nuts (sunflower nuts and pine nuts) ALL over my carpet... I mean it was covered in nuts, I had to clean it up after they left, it was a mess. I thought that was weird. I don't think most sane adults would do something like that?
I don't mind the instability cause I can handle it, I knew going into it that the person was slightly off balance, I didn't know how off balance, but I did know though.
They aren't living with me at the moment. After the fight ( around 4 days ago) they went back to their family's house. They don't know that I know about the hard drives...
