hey dude, i've just watched this. i actually think you approached her well, and she appeared to show a bit of interest at the start. you did great to get her to get a drink with you on the spot. however, i think by telling her you are not sure about her etc etc... at that point it went a bit downhill. please note i am no expert in this though, however it is just my thoughts. either way, you did well, and yes whilst it wasn't a success, you still did something that most other guys won't ever do, well done.
