I don't think that by you not texting her you are sending a message that you don't care. If anything, I think it shows the opposite. That you care and respect what she needs right now and your willing to give it to her.
I know it's hard. If I don't get a text from H at all I usually get really paranoid, and I have to stop doing that.
