Am i over reacting!?!?

me and my mate met these girls on holiday i kissed one but never really new if she was properly interested, there coming down in a few weeks,we havent spoke alot and started talking to her tonight just texting ,i was telling her im doing a skydive and she was like saying how brave and it was and stuff and i told her im doing it for a charity and what the charity was and she just put aaaaaawwwww!! thats so nice and sweet!! i just sent back 2 texts sayin ye its on my list of things to do ect and if she'd fancy jumpin out with me as a joke left it half hour and no reply then i sent another sayin nice n sweet that did make me laugh! see you girls in a few weeks,thinking iv been shot down and as a boy not liking the sweet 'nice' look ...she hasnt sent anything back now and can't see her sending anything...do i just look needy,insecure or just abit of a now....how do i approach it to avoid awkwardness, shall i just ignore it? say sorry if it looked like i was being idiot? ,or just forget about it? as if it never happened..its not a big problem i do like her though
