Sorry for the long post, but please help if you can, I'd love to see this girl again or at least find out where I went wrong.
Went out 4 days ago with a few of the lads to see a famous dj in a club. We drank before hand, popped an e-tab (ecstasy) each and headed off.
In the club, I spotted this hb 9 checking me out. She was on her way out of the dance room towards the bar, and I wanted a night with the lads, not sarging so I didn't take much notice. After the dj set, I was on my way out, and she approached me and started talking to me. She was also on e, so she was a little strange (I was sobering up at this point). I kissed her, she gave me her number and asked me if I was gonna take her on a date, to which I replied yes. We kept talking, I got her home, we fucked. This is the hottest girl I've ever fucked (second hottest would be an 8/8.5).
Next day, she seems quite affectionate. We walk to college (me to get some work done, her to get a bus). En route, she grabs my hand to hold it. I let go after a while to get my phone and she took my hand again when I put it away. We had blast, she was laughing at my jokes etc. being really sweet. Before we parted ways, we sat down for a smoke and a talk (her suggestion, not mine). She complemented me saying I have a very nice body, nice freckles and all this shite. We kissed goodbye. I asked her how I would contact her, as I had her number but she lost her phone the night before (I can confirm she didn't lie about this). She told me to add her on facebook and she'd let me know when she got a phone.
Messaged her on facebook : Well love, you left your cardigan at mine. Lets meet up, I'll give back and we cn grab lunch or dinner. x
Her: hello...pretty sure i mustve nicked the cardigan cuz its not mine! is it nice?? yeh cool, ive a few exams next week but im sure ill need a break from studyin at some stage! bit of an awkward Q but ive completely blanked on what happened wen we went to bed the other night..shud i be worries cuz im not on the pill? sorry just needed to ask x
Me: Cant remember, think its ok not the worst. Ill bring it in for you anyway. As for what happenend when we went to bed, how much detail do you want?

We banged, I used a condom but at one stage I didn't (when you were on top) but I came to my senses, put on another one, and we continued but you were too out of it so I just said stop and then we talked shite for a while and fell aslpeep. I don't think you have anything to worry about. If you're busy with exams, we'll just do lunch, keep it casual. Im around college this weekend but I'll be way too busy I'd say, so Monday or Wednesday would be the best for me. Which one best suits? x
- No reply since (2 days ago) , and I see that she changed her profile picture since, and also liked a photo when she knew I was online (was being fraped so I had a status update). WTF kind of a flake is this? She showed so much interest, then doesn't reply to my messages. Is she toying with me, trying to get me to invest? Has she lost interest? Should I contact her again (by facebook or by phone?)?
Thanks for reading,
Visor.
