I met a guy online. We went on 3 dates. Each one better than the last. There was daily text messages. Things were going well. He sent flowers to my work, suggested future plans for us, talked about become exclusive. After The third date it was a Wednesday I started to have strong feelings for him. We continued to text every day - I had a busy weekend but still made time to text him back. Monday morning was his last time texting me. I didn't hear anything on Tuesday and Wednesday I sent him a text just saying that I hope his day was going well and received a generic response back. Haven't heard from him since and it's now Saturday. Is it over? Any hope? Should I text him?
