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

Hello there users of /r/relationships

I come to you all today, to ask for your advice on my situation. My girlfriend and I had a massive argument after a drunken night of sex, which led to her losing her virginity. She's said to me numerous times, that I can't say anything to her that's going to fix it, and that I have to do something to show her that she can trust me.

At the moment, I'm scared. I'm scared of talking to her, in fear of saying the wrong thing and setting her off. She doesn't want me to give her space, but instead wants me to fight for the relationship. I'm  at a loss as to what I should do. I've sent her flowers, and I'm trying to reconcile by talking to her, but I just don't know what to talk about. I don't want to bring up what happened, because I fear that I'm going to set her off again, and I'm struggling to decipher what she means when she says that she wants to see me fight for this.

She sent me a message saying "Do things to show how much I matter. It needs to be both big and little gestures... I feel like all I'm getting from you is platitudes, and nothing actually gestural".

I'm really struggling here guys. Any help or advice is greatly appreciated. I want to save this relationship, because I love her, but I'm struggling with how I can prove it to her, in a way that will make her believe me.

Cheers :)
