<human>: Give me a shortened version of the text

I've (25m) just gotten out of a 4 year relationship with a crazy woman (23f). We lived together for the whole relationship and seemed to be 100% compatible. We ranted and raved about how amazing our future was and how in love we were. The first three years were spectacular. At the end of the third year the girlfriend brought up the idea of marriage and at this point, I was excited by the idea and I ended proposing to the girl. This is where everything took a turn for the worst.
Her personality changed. Friends saw it. Family saw it. She became much less outgoing, friendships became strained, and even our relationship became strained. During this period, she cheated on me. I decided to forgive her. She began to have these manic phases in which she shaved her head, got her nose pierced, went skydiving and got a tattoo.. all in a month or two. She fluctuating between being happy and sad. She even left me at one point. I had just gotten home from work and noticed all of her things were gone and found a goodbye note on the door. This was out of nowhere! No warning. Just gone. But she did move back in just a few days later. At the end of this turbulent year, she went on a 5 day stretch in which she'd stay out all night and day and not invite me with her. She did not respect the fact that I became anxious when she did this, especially knowing that she'd cheated on me just 12 months prior. She didn't care. After many dead-end discussions, I decided to end the relationship.
This girl went from being the love of my life to someone I did not even know anymore. She became someone that I could not trust.

This is not meant to be a gender bashing question! Obviously, not every female is like the one I dated. I'm only asking for the female perspective and finding a little humor by asking such a bombastic question.
<bot>: ! After being treated so terribly, women of reddit, are there loving, caring, passionate, sane women out there? Give me hope!
