Hey everyone.

This is a bit long winded but I really appreciate if you read it. I wrote another topic on here recently but didn't get any advice, not sure why. But as I say, I really value any advice. The following is not neccesarily USEFUL waffle..but it just sets the background of things. Here goes.

Basically there's a girl I've known for about 5 years now. We went to school together. 5 years ago when we were young (16,18) we went on one date. It was one small coffee and nothing came of it. I was totally in the wrong zone of how to even go about this whole phenomena of women, so as a result, it sort of died out.

So, 5 years on. I'm a bit more grown up as is she. I'm nearing 22 and she is nearing 20. I study down south, she studys up north. Fact. My only means of communicating with this girl is through internet, phone, text and whatever else.

The last time I saw her was at a new years party. She passed out sorta quick so didn't really see much of her.

I've been talking to her on Fbk on and off recently, every 2 weeks or so since NYE. She's kinda flirty but at the time had a boyfriend. Flirting is pretty much her vocabulary I think. Now however, I notice she is single again. One evening I sent her an offline message asking how something went that she did. No reply. I waited 2 weeks to think of what to do. So 2 weeks pass. And this occurs

Me: Stop playing hard to get, it's not working.
Her: you know me too well ; )
Me: Like an open book. Do you have SPAM? It's sort of easier to annoy you on there, Facebook is long.
Her: I don't I'm afraid. I'm very old school you see.
Me: You seriously need to get with it..Cool we'll text it instead then. Text buds. Number?
Her: -Gives number over-

So that's to now. Some of the stuff I said there may seem a bit cocky? Don't know.

My issue

How long should I wait to text her?
How should I build on this? Can anyone link me to any specific long distance texting advice?
How was my approach with her with that convo I supplied (which was 2 weeks after she didn't respond to my previous message)?

I realise this girl is far away and the likelihood of a relationship is slim - in fact I don't even think it'll happen. But I want to build a bond with her all the same.

Any feedback, and general advice is really appreciated. I want to bag this girl one way or another.
