<human>: I fucked up. I am an non-emotional robot virgin who doesn't know how to say no. 

First off, about a week ago, I met this girl from tinder. We texted a bunch and then eventually hung out for the day and that's when everything started moving super fast. She was pretty obviously into me, and my being the stupid pussy I am, decided not to fight it when she started holding my hand. That night we made out and she blew me. I made it very obvious that I wanted to be in a relationship with her even though I 100% did not. I did this because I was a super horny virgin who has 0 self control. 

About an hour ago we fucked. I, afterwards, emphasized that I wanted to be with her. It was only until after leaving her house did I realize how stupid and horrible I was being. Prior to this realization, I thought I would just see how everything played out, hoping that I would end up having at least some sort of emotional attachment towards her because of how already attached she was to me. This, obviously, turned out to be a completely immature and illogical thought. 

The anger towards myself for thinking this was a good idea and sadness towards what I will have to put her through hit me like a bullet on the ride home from her house.  This is my first girlfriend ever (I know, stupid and gay right?) so I have literally 0% experience figuring out how to deal with anything in relation to this. I know how badly I fucked up and how much of a horrible person I am so please save your angst towards me for someone else. 

I know some pain is inevitable due to my immaturity and inability to say no, but does anyone have any suggestions on how I could go about getting out of this relationship without hurting her very badly? TIA
