Stress

I started talking to a girl without having much interest in her at first. Over time, we started talking all the time, and I noticed that I get upset when she doesn't reply quickly. At the beginning, she was the one who seemed more attached to me, but now I feel like my own feelings have changed. I'm trying to understand whether I genuinely like her or if I've become emotionally attached to her attention and presence. I want to understand my feelings and learn how to deal with them in a healthier way.
