<human>: Can you provide a brief rundown of the text in within 3 sentences?

I started talking to this girl roughly three weeks ago having met her at a party, we met up on a few occasions and kissed a lot when we were drunk but never anything more, she told me she was a virgin and wanted to take things slowly, but she wanted a serious relationship. She introduced me to her housemates, I introduced her to my tight circle of friends and it was all great. The last time I saw her was last Tuesday, we had a couple of drinks and a great time. I then went back to her place, we chatted for hours and I left with a kiss again. I said I'd see her whenever as all of our 'dates' had been arranged by me, I was hoping we would progress from that stage into something more serious.

I started feeling ill that same night and I never text her until Thursday, I apoligised for not being in contact and she laughed and said 'it's only been a day', I then started considering if I was being too clingy at this stage so I made a joke about it and decided I'd take a step back in terms of contacting her. We text briefly on Friday morning, I sent the last text and she never replied anymore, it was quite an abrupt end. This is a girl who has seemed VERY interested in me, she almost cried when she thought I wasn't interested anymore a week ago, she introduced me to her housemates and has spoken about me with mutual friends of ours. I haven't heard a thing from her all weekend and I feel so down, she said she wanted a serious relationship not too long ago, I would think that would mean seeing or texting each other at least every other day. But I don't know too much, I've never been in a relationship. Now I don't know if I'm being clingy or not, or if I have good reason to be confused. I feel like today is the day I should definitely call her or something, but I don't know what to say. I'd really appreciate some advice, am I trying to move to fast or is this girl acting a little strange/flakey?
<bot>: Haven't seen this girl I started dating in nearly a week, am I being clingy or is she being flakey?
