Renters Rights and abuse, any one know these specifics?

Hello, I was looking for some details on renters rights and privileges
I moved into this home about a month and a half ago, I previously spoke to the leaser on the phone everything was in order and things seemed to be fair and acceptable, she lives in home with her child and I was to share common space like the kitchen and living room and I was to have my own room that I pay rent for, so far this has been true
the girl and I were reasonably good friends and I assumed the environment would be friendly and cooperative but I was wrong, due to this belief nothing had been written in documentation and she only voiced rules and rights
I will add that I did agree to have a job by this time but as we all know the economy is really bad right now and raking up a few bucks is extremely challenging much less having a career and affording internet, phone, food, rent, transportation and her requirements also
when we spoke I was told that I had access to the phone, the computer and a vehicle that she owns.
After being here for the short period that I have been leasing the room, she is stating that I now must pay half of her phone bill for phone usage, and because she had wrecked her first car I have no rights to the other vehicle and if she uses the vehicle to take me or help me with anything involving my own personal affairs and business I must pay in full for the gas
she has also stated that the propane is being used “faster than she expected” and I might have to contribute cash to the propane bill
also we both buy and separate our groceries but have come to an agreement that we can mutually share specific foods that the other person does not have, she now has stated she believes I am using more food that she is and if I continue to eat anything that is hers I will need to contribute cash for the grocery bill, when I have physically seen her and her daughter take from my groceries and said nothing.
I am not looking for a lawyer I do not want to take this to court or have to type up a packet of legal rights, I want to peacefully and professionally show her that I have rights as a renter and she must uphold her voiced statements even if they were not legally written in documentation
I am tired of the hot and cold the roller coaster of statements she has made I feel unsupported and under privileged
I have payed both months of rent in full and on time, I have stayed by my end of the agreement by including things I was not told to do when I first spoke about the situation, including cleaning her home, chopping wood for her fire place and other little personal nick knacks that were not part of the stated requirements
