<human>: Condense the text into a few key points

My partner and I have a dead bedroom and so on the weekend I used one of the few times we have sex to try make it a new experience. I was rough with her (I would never actually hurt her) and tried to be assertive. I didn't think much of it.

Immediately after she stormed off. She lost her temper at me. She has never been this mad before at me. I didn't do much over the weekend because I knew she wouldn't listen to me or anything. She tells me recently that she's never felt like a victim before in her whole life and she felt ashamed and disgusting.

I feel absolutely appalled with myself. I never knew I upset her like that. She is furious and says I broke her trust and without trust my words mean nothing. She wanted me to pay, physically pay $1000 cos she knows I don't have much money and that's a sure way to make me hurt and experience  the hurt she had. She has since realised this is a bit crazy but insists I show how sorry I am, even though I keep speaking my mind and saying how sorry I am to no avail.

How do I make a grand gesture? How do I show I'm sorry? Is there a way out? I just don't know what I can do to show how sorry I am I made her feel used and like an object.
<bot>: Upset my partner with expirmental sex. She says I broke her trust so words mean nothing to her. How do I heal our relationship?
