Hey NJB,
Like Hue said, it is better to hold back on the amount of texting, to avoid the textbuddy loophole. And it is better usually to incite her to talk about herself, rather than you doing the talking. However, yes, when she's away and there is no possibility of meeting right away, you've got to keep the connection alive, so you have to use this chat.
But what I suspect you are not doing, and which cost you the interaction, is: you did not maintain a healthy sexual tension. Correct me if I'm wrong.
How would you do that?
First, you're not always available for texting. Sometimes you don't answer right away. Sometimes you keep silence for a few days and let her wonder. You aim to let her initiate the chat, say 2 times out of three. A reasonable dose of silence in texting is a good habit. It keeps her guessing and keep her on her toes. If you're too available, she will guess many things about you, such as you're obviously not busy fucking someone else. She should never be sure of that. Nor of the opposite.
Second, you make sure that you keep some sexual tone, at least once in a while. Use and abuse sexual innuendos. Make some references to her womanly shapes in her pictures. Etc...
Third, if you are going to call her, you are going to use your sexy voice. It's the first physical contact she will have with you: your voice. Remember that your voice alone can make her wet. Read on GC main site the articles on fundamentals and on voice. On the phone, you will keep a cool and collected tone - as opposed to a hyper excited one. You are going to avoid making her laugh. If you don't understand why, I suggest you read "making her laugh means nothing" from Ricardus on the main site. Your call is going to be about keeping tension.
Tension, tension, tension!
Just a week ago, I went to meet a girl that I knew from Instagram. Same, long distance situation. Here are some excerpts of texting we did before meeting:
Me: You also work on your fitness. I will control the results! she was hinting on having gained weight over the festive season. That's a very common girl concern and a nice way to get sexual
Her: Will try
Me: Are you still able to put these tight jackets and button them around the waist? direct reference to her Instagram pics
Her: Yes
Me: So what’s the worry?
Her: The hips
Me: A little more fat around the hips will just add to the charms (wink)
Her: Hahaha (laugh emojis)
Her (switching subject): Do you know that I have never had a white man? (drops / aubergine emojis) - she's a black girl by the way
Me: It means it’s about time you tried French food! I'm French. Insert any nationality here.
Her: Oh yes
Me: Hahaha. I have some experience with exotic dishes already (wink)
Me: But Ok, you need to be initiated to French cuisine. We have some nice chefs!
Her: Haha really? Am waiting
Later on she kept referring me as "my French meal", while I was calling her "my hot chocolate".
Note her reaction when I mentioned her charms - she said she never had a white man, implying she wanted to fuck me. That's the sort of reaction you get when you hint sexuality. The drops and aubergine emojis are a direct reference to a dick and sperm.
This sexual tone kept her interested, and when we finally met (some weeks later), she was in my bed about 30 minutes from first meeting ever.
Sexual tension! That's how you are going to keep the interest up. Try it!
