Am I wrong to cut her off?

So I met this girl last month at my school. We connected instantly. We will talk all the time, bought each other, food and gifts, and just really enjoyed being around each other. I found myself opening up to this person, which is rare to me, given that I’m not a people person. But, naturally I began catching feelings for her. Every time we talked or hang out, it was always hard to say goodbye.

The last time we talked, I thought everything was fine. She walked away, giggling and smiling, offering a goofy goodbye. Days later, I texted her about checking out this campus event together. She never responded. But continue to post as normal, even liking my photos. I brushed it off, assuming she was busy. But weeks went by. I’m considering blocking her on everything. Because mentally I’ve detached from the situation and I’m honestly over it. Would I be wrong?
