Call her. Texting sucks. Quite honestly, I hate delayed responses. If you talk to her on the phone, you will get a synchronous response instead of an asynchronous response. Texting is like sending someone an email. They will respond to it when they want to which could be never depending on what you say.
Everyone on this forum could vouch for me when I say that I texted way too much. I just came to the conclusion that I would stop being a whimp and just call, and it's actually helped out so much.
Women can be two-faced when it comes to text messaging anyway. They will tell you something on the phone different from their text message. Don't even text to make plans. If she texts you, then fine. If she doesn't, call instead of text, but never call saying "did you get the text I sent you?" That will make things awkward fast and the result won't be good.
And also, wouldn't you prefer talking to her? Your conversations will be more fulfilling if you talk to her on the phone rather than trying to text her.
