So will try to make this simple. I met this girl, we went on around 5 dates, hooked up a few times, and then winter break hit. She started to text less over the 5 weeks and then when I didn't respond to her text within a few days at the end of break she asked if "we were good?" I said yeah, we texted a few more days talking about mundane school stuff and then when I asked her if she was free over the weekend she went MIA and ghosted me.

On a side note before I left for break I decided to have the conversation about where her head was at regarding exclusivity because I didn't want to make a mistake while I was home and didn't want to hurt her, but hindsight I should've never done that since I had no intention of dating long term (i.e. because I am graduating and moving back home which is no where near where she wants to be). She didn't really want to talk about it and I pushed the issue, rambled on and to say the least made it awkward and I think made it seem as if I wanted to start becoming more serious, which was not my intention as all I really wanted was a casual relationship.

So anyways about a month goes by after I sent the last text asking if she could meet up and I was walking on campus and saw the girl walk by me, just said "Hi" and she acknowledged me and that was about it. Well she then texted me asking if it was me who said "hi" and now she is asking about "how I'm doing" and giving me reasons as to why she didn't text me back (hanging out with friends, etc.). So my question is, if I only want something casual and nothing more should I text her back or should I just leave it and look for something else? And if so should I make my intentions clear to her immediately and if so how?
