Been dating a guy for the last month. We've had 3 amazing dates. Hes been consistent with communication like texts & calls. All postive. Tuesday night he asked if he could see me wednesday afternoon but come to my house. I said that was fine. We carried on talking, again all postive. Tuesday night ended the conversation with our usual good night messages. Wednesday morning he didnt text me good morning like he usually does so I waited a while then messaged him "good morning" at 11am. He never read it or replied which was odd because he usually replies within minutes. I got on with my day & thought I'll give him some space. Its now friday & he still hasnt read my message or replied & I dont understand why so about 4ish today I sent a check in message "hey havent heard from you since Tuesday. Hope your ok" again hes not read it or replied. Im really confused about what has happened for him to suddenly act like this when its been so great & positive. Any advice?
