I think this girl is ignoring me ?

I text this girl that I thought she liked me but anyways I texted her if she wanted to go somewhere with me and freinds and she hasnt replied back to me and this was almost a day ago I know she got the text tho cause she always checks her phone and I saw her in the halls today and I didn't notice her at first then as after she passed me I relized that when she saw me she turned her head so idk if I should go talk to her next time or what I'm kinda bummed right now
