I have known this girl since we were both young but this year when we have been home from college we have rekindled our friendship and now I would like it to be more. Right now the signs mostly are that of a friendship. We occasionally invite each other to social events or parties. There have been some signs that she might be interested (although I may be reading to much into it) such as last week she wanted to go on a hike and when I suggested that we go with some other friends who were going for a hike she suggested a shorter hike but without anyone else.
Anyway what I would like to do at this point (by building attraction) is make her more receptive to texting and more eager to so things. Currently (like most friendships) she ignores/forgets to text back and he busy schedule makes it hard to make plans work but I feel like if there was some (more) attraction on her end things would work out more easily.
What are specific techniques to achieve this with a girl who has seen me as a friend for a decade?
