No disrespect or anything...but chances are if she can't stay off her cell phone during your date, she's really not that into you to begin with. During a date, if a woman is into you, that cell phone will not make an appearance until she has to run off to the bathroom.
no I had a girl do that. excessively too. I took her to lunch, paid separately but I acted like a nice guy. she started texting friends or something..
I, like you, figured she wasn't all that into me and well, maybe she wasn't at the time.
Fast forward, I'm well drunk in the club and our pathways cross once more. This time I act like a total douche instead since I remembered the unfulfilling date, and of course it ended up at my place for a good "service".
Moral of the story. Act like a obnoxious brute. And the cellphone move is not a catastrophe.
