<human>: Can you summarize the given text in a few sentences?

My partner (F/21) and I graduated college this year. She has a home (funded by her parents) and I have most of my belongings her house. I do not pay rent there and I did not sign an agreement/lease, but I have been traveling recently and kept my belongings there and stay there when I'm in town. 

The relationship has been growing progressively more sour. She is emotionally and verbally abusive. She has also hit me on a few occasions and she has also hurt herself in the past. I was a highschool varsity football player once upon a time, so I am on the larger side, and am not hurt by her fists, but I worry if things escalate to weapons like knives in the kitchen. 
  
I want to get out of this relationship and move my things out. I dare not say anything when out of town as she will trash my belongings. While staying at her place I am worried she will become physically violent. I wish I could call the police and say "hey bring an officer here since she will be getting violent" but that's not how it works. 

I see two options:

1. Move out on the weekend while she is at home. Recipe for disaster. Friends can help me move. Them being there might tone down her aggression.

2. Move out on a weekday while she is at work and rush to get it done. Hire some movers to help get it done quickly.

Questions:

1. Out of option 1 and 2 above, what you think is best?

2. If my property is at her place, is she allowed to trash it and not face any consequences? I don't pay rent and don't formally have any stake there.

3. Can I audio or video record the move? Will any of that evidence be permissible in case she hurts me or not since its private property?
