<human>: Can you give me the gist of the text in a nutshell?

Alright so ever since the spring this girl has had a crush on me. I thought really cute too, so at work we would playfully flirt with each other the whole time.Im 20 and shes 18, anyway I really didn't want anything to come of it so I just left it at playful flirting,(it was so natural to flirt with her I didn't realize how much I was doing it), I started flirting a bit less but it was too late, she already had a huge crush on me. So the other night, I had to give her a ride hom and she invited me in for some pizza, and in no time I made a move to kiss her(first kiss btw, good boost for my confidence, but now I feel like a piece of shit for ending up in this situation) in the heat of the moment and we ended up making out for a good 5 hours. Waking up the next day I felt a bit confused, I couldn't tell if I was attracted to her or not but later that night after work we were in my car for a good 5 hours again. 

Now I sit here upset and confused, she's an amazing person and shes funny, smart, and really easy to talk to.(Shes also going away to study law at a college about 1 hour away.)I feel like this was the reason all along that I didn't make a move on her earlier. Now I feel like a piece of shit, she's really into me and I can tell. I'm confused.
<bot>: Made a move on a girl who was really into me, made out with her a lot, now I realize I'm not that into her and I feel like a piece of shit.
