And he left me out...ne'er mind!
This is my take on the matter:

You have started well with the texts, reminding her who you were, the thumb fight, sign language, slight negging etc etc. If she hasnt texted you back within two days, text her again but dont mention to her about the thumb fight anymore. She probably think you got nothing else interesting to say...! Come up with something completely random to get the texting going again. SOmeone posted this text a while back "e.g. white top or black top". Or a few weeks ago when the weather was scotching I texted this HB "trainers, sandals or flip flops?" and she would immediately reply "flip flops, why?" Then you explain why and start the textin going again.."hows you been", "havent heard from you since the last text", fancy going for a drink on Saturday"...I think you get my drift.

Anyway, thats me and my text game. I hardly ever speak on the phone. Just text, arrange a date, meet up and have a good sexy time..!

Does it work? Well, it works for me! Each to its own..!

Much Success....
