A girl I had a small fling with, seems there wasn't enough interest to keep something steady and consistent because when I would message her she would deliberately ignore my messages. However, then a few weeks later she will message saying only "Hi" ... pretty weird texting habits but also she is young (19) while I am 24 so maybe more mature in my communication. Not sure how to approach this situation though. Normally I would just ignore a girl so inconsistent, but with close friends or girl I found cute like her I'd probably still respond even though they pissing me off ... any ideas?

Keep in mind I realized it was almost always me initiating conversation; we she was initiating it was very bland and boring with little effort behind the message besides a "Hi"
