<human>: So me and this girl dated a bit, lets name her Jess, but decided to broke it off. Jess knows my share of the story with my ex, lets call her Emma. (I have been treated like shit). At a point when we dated Jess talked with Emma. I have no idea what they talked about. Then me and Emma became "friends" again. Well, ever since that, Jess has been extreme hostile, arguing all the god damn time about anything. 

Emma said that she wanted us to be friends and made me promise i will try. So i tried and then she literally ignored my existence. Nothing, not even hello. I Jess about that and she literally attacked me(verbally) . Its like she feels obligated to protect Emma from anything and shows no compassion towards me and never tries to understand me.

I am trying to fix things up with Jess because well, i enjoy her company when she is not angry as heck. She had promised to argue less, or at least she would try. But its always her attacking me and always i have to apologize. She attacks me with stuff i thought i could tell her because i trusted her.

Can you condense the text into a few key points?
<bot>: dated a girl, mutual agreement to break it off. She talked with my ex, became extremely hostile towards me and shows no compassion.
