Leah, try to get off the rollercoaster and reach a place where your mood is not determined by what he is doing, whether he is contacting you, and whether he is coming. Read your recent posts again. There is an awful lot of excitement and expectation and excuse-making going on there. Try to let him do the reaching out. Now you will never know if he would have contacted you while he was there. You knew he would go through a period of withdrawal after you guys spent the time together. He is acting according to script. You need to do the same.
