Edit:
oh hell ... didn't see the 'IM' in there and wrote something different
) .... well if the conversation is going well and she enjoyes it, than what she says must be true, if you see the girl is not investing to much in the convo and doesn't really want to talk to you it means you're not doing it right ... also, C&F is not to good for IM convos because you can't express it right, maybe with some emoticons or so but most of the times it can be misunderstood and you will appear as only cocky so go ahead in the real world and practice it.
