Still even if she is "pretty sure" u like her and u said u would call..text..it is the much more common laid back approach which ~can~ lead to a hey lets chat on the phone later/call me when im not driving/lets meet up at the local *meeting place*...
I had to explain this to my girl this past week, and I hope this comes across the right way =D
There is only one time in your relationship you will get to have the first thrills of "does he/she like me, zomg wonder if he/she is thinking of me whatnot"..
Chances are she is sitting there with her dreamy little eyes all sparkly going " I WONDER IF HE REALLY LIKES ME AHHHHHHHHHHHHH " To her girls~
yes women of ALL ages do this I have found out
She will be thinking of you all day long BECAUSE you have not called yet, and once you do that finger nail biting suspense is over :P
