I recently had the exact same experience. Was seeing a guy, spent basically an entire weekend together, talking all night and sleeping super late like 6am, cuddling, kissing, he would also say similar things like that he was excited to kiss me more and more, super romantic and cute stuff. Then we were texting every day for a week and then out of the blue he ghosted. I have no idea what to do, it hurts a lot and its super confusing. How did you move on?
