What should I do if she doesn't respond to a text?

I asked my crush through text that if she wanted I could take her to a movie next week and she hasn't replied. This was at 1 in the morning so she could have been falling asleep or she was working. It's lunch time right now and I still not get a response. She does reply to my text eventually but at the same time Iv asked her out through text before and sometimes she replies and she thinks it's sweet and other times she doesn't even reply back. I feel like an *** asking her but I don't think she would blow me off because she says she works everyday and she thinks I'm hot. Should I just ignore what I said.
