Not quite sure what the problem is..there doesn't seem to be anything to 'approach' on a second date. It sounds like you had a good first date, and are happy to have another one. I wouldn't worry about what is going to happen in the future with this person until you get to that point. Enjoy the initial dating, and learn more about her - and let her learn more about you. Talking about what you want for the future with her this early might be a bit much. Good luck with your second date!
