Yes, what Artista said. Detachment is key and the sooner the better. I think you know a lot of your behavior was heavy pursuit as when you described it you mentioned not having read DR yet, so I think you probably already know this, but stop the pursuit immediately. Read the book, read Cadet's links. Read Sandi's rules and follow them. Read them every day or even several times a day to remind yourself of how to behave around him.
You mentioned doing a 180 on not showing him love, NO do NOT do that right now. It will just drive him farther away. You can't fix that right now. Detach, get out, GAL, work on yourself, leave him alone. Don't initiate any R talks EVER! Right now you look sad, lonely, desperate and needy to him. Your goal is to turn that around and start looking strong, independent, desirable, valuable. The first will repulse him, the 2nd will attract him back.
