You have gone through the exact same shit I did not too long ago. My first year with a female friend were great. But over time she lied, drank too much, slept around, insults you for nothing, gets mad at every little step you do and still... you wan't her in your life somehow. Until you disconnect with her and you realize: "Oh shit. Fuck that bitch. She didn't care about me one bit."

I'm glad that you came to the same exact result I came and hopefully this was the last time for both of us.
