Amelie, honey, first of all....please don't let yourself be "bummed out" about this. I could be that you will still hear from him, but my intuition tells me that if he was sincer he would have called you sooner. Now...what if he does still call..LATE, to suggest getting together for the weekend. My response to him would be, "I had hoped to hear from you, but since I didn't, I have already made plans." Then suggest if he wants to see you again to contact you (sooner!!!). Don't let him think you are awaiting him holding your breath!
Have you read HE'S JUST NOT THAT INTO YOU? It's a kinda silly book, but it does tell how men behave when they are desirous of a female and I read it when I was being rejected. It was an eye-opener!
