Why won't this girl text me back?

Well...sharpie, i think your just fallin for this girl faster than you think. Girls sometimes don't want to come off as being desperate, so we try to make it seem like we r not, by not exactly texting back right away. This may be what she is doing. Imean she obviously is interested in you, she just needs some space. and you have to be the better man and respect that. :)
