Before I was going out with my gf I once waited for her for 4 hours in a mall and I only moved once to get somthing to eat. She is well worth the wait. if she says she will be 15 mins and turns out to be 1hr don't be angry or depressed. Keep waiting and be happy that she did come. I agree with the above. Talk to her and make sure she knows that you are intersested but don't sound desprit. Don't try to rush things just take it slow.
