freeze outs are harder the more you know sumone...
but distance makes the heart grow fonder, if its not to serious SPAM a day freeze could be good, and you can always say after "ohh i was just busy at work" but wait till she contacts you...
about the kiss - remember ppl have alot to deal with in life, and it all affects relationships, she wouldnt have kissed you if she didnt want to. if she seemed attentive when you were talking but then went awkward when you kissed her that would be the mistery of a womans head!
give her the benefit of the doubt. but remember ur the prize, so dont go mollycoddling her.
alot can be said for a freeze
hope this helps
good luck
lets us know how things go
