Super quick tip. If you happen to get a cold shoulder one day, just try again later. Girls are so tempermental and have so many mood swings. It likely doesn't even have anything to do with you.

Even if it seems she is ignoring you today for some other guy, just try again tomorrow. I hate to say it like this, but they have such ridiculously short attention spans, the most important thing is to be first in line.

That is all. Don't get ass hurt, just wait and try again later.
