You like this girl, but you might not be what she needs her life right now. You're focusing on what you need which is a romantic relationship. The ideal is that you think that she's perfect for you. The reality is that you might not be perfect for her.
With all relationships, you focus on what you can control. You can control asking someone out to dinner. You can't control if they say yes or no. You can't control if they have a good time. You can control whether you have a good time. I find the people who are responsible for their own happiness are the ones I want to be around. I don't feel pressure that I have to be responsible on whether they enjoy themselves.
So she doesn't want to date you. At least she's honest, instead of dating you because she doesn't really care that much and she doesn't completely dislike you and then breaks up with you once she gets bored enough.
Have you considered why you feel bored with girls that show interest in you and that might be the same reason this girl you like doesn't want to date you? With the girls you broke up with, what would they need to have done for you to be interested? Could they have done anything at all?
