First off, Movies to girls either = boring or = He wants to make out for 2 hours, she wont really be all that interested unless it's a chick flick...but in either case why would you want to go to the movies of all places. You can't convey your personality and get a girl interested in you while she's trying not to fall asleep in a dark movie theater.
And don't assume so much. Work is important and I put it over getting together with any girls that I know, and most girls do as well. I'd say put this one on the back burner for a while and myabe ask her out again in a week or two.
But this time have something fun an interesting to do!
"Hey, I'm going to this party tonight, it's going to be great! We have an ice luge, a mini bar, and it's PIMP an HO themed! Going to be a crazy good time!"
Now I'm not saying do THAT specifically, but do you see how much more interested ANYONE on average would be in doing that rather than going to a movie?
Even going to a really popular area of town and walking around where there are tons of shops, places to eat, and neat things to see is 10X better than a movie. And this is more of an adventure for a girl.
I grew up in a reall small town, 4k peole or so. About 10 miles away was a city of 70k people. These were the only 2 places people used to hang out....somewhere in our small boring ass town or go in the "city" ...one of two popular places to chill. Everyone knew these spots, it was a very predictable place to go, nothing new nothing interesting.
So I thought to myself, how the hell do you be a little different in this situation? Well, most of these close minded and lazy people didn't even bother to notice that 20 miles away was a great beach / amusement park / tourist / party spot to have a great time and no one I knew went there on a regular basis. So, O drove there by myself once and setup a little "10 stop adventure" to all the cool spots in that area...found interesting places, thought of 1-2 interesting things to do there (just in case), and would take dates on a "New and cool adventure" on the _fisrt_ date and that set me up as the "fun guy to have an adventure with" instead of "go to the movies guy" like 90% of the other guys she knows.
Just a tip. And don't think anything is ever 100% blown unless YOU really **** it up by being REALLY mean and insult the **** out of her or something equally terrible, feelings always change over time.
