Right, this is my problem and I'll try and state it in as few words as possible to make it easier for people reading.
There is this girl whom I met through work who I am quite interested in - I wouldn't say I'm desperate but she is quite interesting none the less. So I decided I would put my charm to work and try and do something about it. Okay firstly she is young (perhaps even too young?), 17 and I am 20. From the start I had a small suspicion that she may have been interested but wasn't too sure, but was willing to try my luck anyhow. So at first I got to know her by having small conversations and made myself a friend at least - this only lasted about 2 weeks. I then persuaded her to join a group of friends and myself who were going to a bar on christmas eve, and even though she knew noone going there except me she still said yes, and actually gave me her number so that she could phone to make sure she could find us alright. So you can imagine at this stage I seemed pretty sure she was at least slightly interested.
Well anyway after obtaining her mobile number we started exchanging text messages every few days or so and I was out on new years eve and (after a few drinks) I sent her an SMS and asked her if she'd like to meet up. Her reply was "I'd love to meet but I'm not leaving the house until after exams, but then sure". Not entirely negative but a bit of a blow. So I still continue to keep in contact and there was definite flirting between us. In one text she said I was sweet and even admitted to liking me, which only makes this situation all the more confusing.
Fast forward to after exams and yesterday I decided to ask her out again; I sent her a text and just said "Do you still want to go out, how about some stage next week?". Her reply was again a little disappointing, something along the lines of "Sure we can go out sometime but I'm fully booked for the next three weekends as four of my friends have 18th birthday parties within two weeks". It makes sense as she is in her last year at school which makes her friends the same age as her but to me it seems she is just putting things off again. Why do you think this is? She has already admitted she liked me through her text messages and gave me her phone number without me even asking, but yet every time I ask her to meet it's always put off. I'm not even too sure what to say back to her, perhaps I could say something about meeting during the week, but I have a strong suspicion she will probably reply with another lamish excuse, perhaps homework or something like that.
So what do you think? Do you think it could possibly just be down to shyness? Or do you think she initially liked me but perhaps doesn't any more? It's so weird! Should I suggest meeting on a week night? Or maybe even wait until after 3 weekends? I really don't think I can be bothered waiting again although I do like this girl so I'd like to go out with her at some stage. What do you all think?
By the way I apologise for the length of this post, hope you had time to read it all!
