How to bring up my girlfriend texting habits at times bothers me without sounding needy or insecure?

So my girlfriend I’ve been dating since late November at times her texts come across as dry and i feel like I initiate a subject change or keep the convo going a lot of times. It’s starting to really frustrate and annoy me because I feel like she doesn’t want to text or that I’m bothering her. How do I bring this up without coming across as needy or insecure?
