i been through almost the same thing.
and to let you know she didnt change over night, she was feeling something and she decide to tell you.
i was happy with my ex, and he told me he's moving out and that he wasnt happy. we stayed together and moved in a house together, and a few months he told me he want to date, and he was going to treat me bad until i left. this man soaked up my money, feelings, love, everything. ive been with him for five years.
i got my apartment, job, lost both of them and had to live in a shelter.
so i know what your going through. i would never live with a man no time soon. i have my own place and i like it that way.
my advice to you is sit and think about what your going to do, where your going to live. and move on with your life. i know how hard this will be for you, if she doesnt deserve you, i m sure another will.
dont think it's just you, so many women feel the same way.
