Her: I just want to make it clear. I just want to be friends. I don't want to mislead you.
So what if she said that? No matter what the case, you can always
CREATE interest in her.... but by making the dinner a boring one you will NOT be creating ANY interest in her...
Some ways to CREATE interest:
1) Make her laugh
2) Make her ENJOY her night (eg: NOT be bored)
3) Take her somewhere nice where you WONT get bored, maybe a comedy show, or a dinner somewhere where there is maybe a band of something going on, or even a nice dinner and just simply show her a good time.
4) Be talkative, and DONT just sit there and wait for her to make the conversation.
5) Try find a subject that she is interested in, and talk about it.
6) Make her feel special / good about herself, so compliments her, NOT alot, but throw in a complimet here and there, and try make your compliments be original, not just the everyday " oh u have nice eye's" or " you have beautiful hair" etc.
7) Be charming
8) Be confident, be the alpha, DONT BE SHY!
9) Help her out with any problems that she might have eg: other guys, parents, friends, etc ( Most people wouldnt say this point, but from what i have seen, they appreciate it so much, and thats a good way to "score browny points" with her)
10) Respect her ( Dont tough her or do anything TOO intimate or "romantic".... yet

)
Well there are a few things that i suggest u do next time (if there WILL be a next time... and if not with this girl, then know this for the future)
I hope all goes well for ya...
Laterz.....
