I guess some people never learn

How do I manage to always forget the stuff that I have been through and  just get myself back into the same nonsense. I guess that I have a problem or a need for a complicated life.  I now have the same annoyance that I had back in 2010. Roommate, well live in nanny, this should be a helpful thing because I have the help, but because she keeps touching things I ask her not to I have lots of frustration.  I guess I just need to keep repeating myself and hope that someday it will stick. I should be grateful that I have the help, and trust me, I am. I just never thought I would allow myself to get in the very same situation that I hated so very much two years ago.
