Most Helpful Girl
She dumped you because she felt you Wernt into her as much as you...
This is obviously all the more reason you should tell her how you really feel. You don't need to bombard her, you can let her know that you know you blew it before because you didn't make her feel appreciated but you've kicked yourself ever since and just want another Chance to prove that you are into her more than she thinks.
The reason so many potential relationships fail is because everyone has to much pride to say how they really feel which results in mixed signals and break ups!
Needy and upfront are 2 different things. If she's meeting you chances are she is hoping you still want her but she probably wants you to make more of an effort!

I think you're right to avoid appearing needy, but at the same time you have to be ready to go with the flow if the opportunity presents itself. You can flirt a bit to get the ball rolling, and see if she's interested. Don't reveal until she expresses interest.
