How bad is it?

I've been talking with a girl who is basically an acquaintance but I am very interested in actually getting to know her better.  We were both in one of the business clubs last year in college which required business wear during formal meetings so I at least made an attempt to dress well, but I'm 5'10 and fairly broad chested so there's only so much that can be done to make me look less imposing than a brick wall.  Meanwhile she is about 5'6 and probably somewhere in the neighborhood of 130 soaking wet and young enough that when we first met I had to double check the age rule.

Anyway, after one of the meetings had wrapped up me and this girl were talking about just random stuff.  She had mentioned a complete lack of sleep the night before and how she was trying to break out of her shell a bit since she was an introvert.

*Ah HA! I thought maybe now I can be smooth*
Me: "Well if your up for it I'd love to take you out to dinner later this week."
I said it with a straight face, no stuttering, and not smiling like a psychopath.  Success right? Not f*cking likely.
After I finish my proposition she kind of freezes like a dear in the headlights and practically squeeks out "I...don't...know..." with an awkward kind of chuckle and the conversation kind of peters out from there, but she doesn't suddenly make an excuse to kind of book it away despite there being ample opportunity.

My last relationship kind of killed off a lot of my self confidence, long story for another time after I've had a few pints, so I'm kind of chasing my tail trying to understand what should be basic stuff for someone my age.
<bot>: Awkward AF college guy trying to understand if equally awkward response from the girl is actually actually the knock back, or an invite.
