Title says it all
Most Helpful Girl
@Anonymous - Maybe you're feeling uneasy because she didn't reciprocate the communication, that if she liked you that way she would have easily responded "Thanks! How are you?" or continued the conversation with "Thanks, you too! I think works going to kick my butt today tho -_-" I also think taking the fact that she responded at all as a positive may be a red herring. It takes minimal brain power to type such a generic response and it's more disadvantageous for her to ignore you - no one wants to feel like a shitty person if they can help it.
Or, you could just be really into her and nervous about whether the feelings are reciprocated. Like my fellow ladies stated below, she definitely did not give you a reason from this message to doubt that she feels the same way. More background is needed to say for sure cuz without any details we could blue sky all day about it! ;)
I wish you well and hope it works out!!!1
