Girls can you help me out?

Lol well it helps that your a girl. I got some girl troubles I kinda need help with. Well its not really troubles but about 3 weeks ago I took a really sweet girl out to dinner and we had fun and we still talk all the time. But I've asked her to go out again and she kinda ignores the question. But it was a long time since I took a girl out cause I got out of a long relationship so it was a while, I didn't do the things that a gentlemen should do when we were on our date like I didn't open the door for her and didn't walk her to the door at her house. Just the simple things that I should have done I didn't do and I'm kicking myself in the *** for it. So would you happen to have any suggestions for me of things to do on a second date with her and how do I get her on a second date? I really like her a lot and I wanna show her that.
