Should I let it go?

It's just a question. I feel 50-50 so maybe little feedback or insight might be helpful?

I know one girl. She is quite younger than me (is it rude if I mention she is a virgin?). I know her for over a month.

She is a bit odd but than, who is not? At first I though she is all right and but now I feel every indecisively about her.

pros:
- we have (probably) commons sense of humor.
- talk is rather easygoing and OK. But nothing remarkable.
- so far she seems to be very responsive every time I write to her.
- quite cute and lovely!
- usually I feel fine when talking to her.

cons:
- we are way different and beside joking there isn't probably single common interest.
- I did not met her in person yet (yes, I know. internet...). I don't know for sure if I will be attracted to her physically.
- At first she was all eager to meet but I had no time. Now I do and she seems to be hesitant with obscure reasons.
- I don't judge people, but she seems to have self-image issues. Usually I don't care but this time it is becoming slightly annoying. Maybe (likely) she act weird because of that.
- looks like empty personality to me. Or at least based on what she told me. No hobby (beside browsing internet), no career plans or ambitions... (she is young, a bit understandable. It is not that rare to meet people with same attitude over 30...)


First she says she is "no lifer", I almost feel pity for her, now I suggest "let's visit cinema" and suddenly she is all too busy. Let's meet on this weekend - "you can't suggest date just one week ahead! I have to make plans". Honestly, this **** annoys me.

I feel very hesitant, 50-50. Honestly, none of my friends is problematic or odd acting person and if he is, he usually ceases to be my friend. So... I am thinking is should I move on or push it further...

Maybe the answer sounds clear but than... virgin... very pretty female friend... probably bi... (yes, I know, I am a pig. But hey, I am men! ).
