<human>: I recently met a girl through an online dating app, we met up for drinks the first night and hit it off pretty well (given the first date jitters). We decided to meet up a second time and went to get frozen yogurt, this date went pretty well but I did get slight annoyances by certain things she said ("I don't know, im just a bitch sometimes, LOL" 

For the third date she invited me over to her place for a home-cooked meal, I had my apprehensions but went anyway. 

it went well, we ate dinner and joked around but I still had a little voice in the back of my head telling me this wasn't going anywhere. Later in the night we were watching a movie and she grabbed my hand and placed it on her thigh; a little while later I put my arm around her and she started to kiss me (she leaned in to kiss me first, but I definitely wasn't fighting it).

we ended up sleeping together that night (2 nights ago now) and i stayed the night feeling pretty good, thinking that I was really starting to like this girl.  The next morning we woke up and she kept saying how into me she was, and how she has a huge crush on me which left me feeling a bit bad because I'm sure I don't feel about her what she does about me.

I am not saying that she is a bad person, but I feel if we were to continue on this path it would end pretty badly in the near future. So i would much rather end it now and save face for the both of us.

My problem is this, I have never ended a relationship before (always been dumpee, never dumper). I feel like this shouldn't be too much of a problem since we've only been together 3 times, but us sleeping together definitely throws a wrench in the gears. How do I end this without making her feel like I used her in anyway?

Can you give me the gist of the text in a nutshell?
<bot>: I dated a girl 3 times, we had sex, I don't like her enough to continue and need help ending it cleanly.
