Met a guy through work, got to know him at weekly visits we both attended. He asked me out - went on 3 dates, it was so intense, lots of texting and saying he couldn't stop thinking about me, both saying we felt like teenagers. Decided to sleep with him, was a great night, but he's now cooled off. He still texts and initiates conversations but doesn't reply for up to 24 hours.
I'm an idiot obviously, but how do I put this behind me and stop thinking about him every 30 seconds? It's driving me crazy.
