Yeah be careful man, too many texts just about general chit chat can often lead to the friendzone. If you are trying to shag this girl then you should be more selective with your texts and aim to hit the points needed to get her into your bed (attraction, comfort, trust etc.) Dont always be the first to text as this is a sign that the girl has power over you, and she knows it, therefore its no fun for her and isnt a challenge to get your attention. Also you could try adopting the cocky funny approach in a few of your texts and see how she responds to these.
Like mentioned above, there are plenty of helpful threads about texting games on this forum. From personal experience, ive been texting a few girls, playing some interesting different games with each of them to see which works best. Cocky funny without sounding too desperate for sex at the same time is a big winner so far. Demonstrating value by talking about gym, hanging out with other girls, and sex openly with her, without sounding like you want to sleep with her has worked for me. Throw in a few soft negs aswell, but if they go bad compliment to save yourself. And arrange to meet up or something, but tell her dont ask her. And leave it a secret, tell her a time and what she has to bring or something, and make it fun
