OP, the advice you've been getting here is solid.
Here's what I've seen -
1. You keep texting her vying for her attention. Instead, just focus on setting up the next date. Listen to the guys above and also read R.C.'s texting guide.

2. This one is more in general. You spend way too long thinking about what to say instead of just going with the flow. Tease her, pull her in, challenge her, keep her on her toes. I tease every girl I talk to, not just ones I like, but I don't accept the advances of interested women whom I'm not attracted to. I've got options. Get it? Abundance mindset. Develop it.
3. You're pleading for a call. You left a voicemail, then asked her for her opinion / asked to call her, then when she asked what you wanted to know you didn't respond because you were too busy thinking of what to text next / say on the phone, ... neediness. All this wanting to call her and talk is way too eager and needy. Why do you want to talk to her so badly on the phone?
