<human>: So I'm a 19 year old male straight sophomore college student and I just got in my first relationship since the 10th grade of high school. I met this girl on OkCupid because I'm too (though I feel like it is now 'was') much of an introvert to actively seek out a relationship upfront. So over the course of a month we go out on several dates and last weekend we decided to spend the night together at her apartment on campus. 

Up until that night I was a virgin so the sex itself was awkward, but at least I thought, the foreplay was amazing. I go home the next morning because I don't live on campus and work on the weekends and I get a phone-call from her today saying that she realized that she just wasn't ready for a relationship. 

I'm not the type of person to get angry and by the sound of her voice she seemed a bit emotional. So I don't think that this is just one of those cliche bull excuses like "its not you, its me". 

I asked her to explain and she said that she had been thinking and just couldn't do it right now and she wished that she realized it earlier for both of our sakes. 

I don't have any experience in adult relationships (as my last relationship was when I was 15), so I don't really understand what happened. I mean I get her explanation (I think), but I don't understand why she would let it go as far as her taking my virginity if it just ends there.

Provide a brief overview of the text.
<bot>: First relationship in 4 years, get virginity taken (wasn't bad), get told she wasn't ready for relationship. I don't understand.
