So there's a guy in my grade at my school who everyone says likes me. He always looks at me, smiles at me and waits for me just to say hi or to ask how my day was. A few weeks ago I dmd him with my number and he just saw the DM. Last night he texted me and we talked a bit today.. until he left me on read. It's been seven hours. I want to give him the benefit of the doubt but at the same time this has happened to me so much... a guy acts like he likes me, is charming, then stops talking or leaves me on read. I feel like I might be being petty, or maybe too cautious, so I wanted your guys' opinions. Is this petty? What should I do?
