Why hasnt he called after our great date?

I know!!!! This is a common occurrence and it has happened to so many of us. You had a terrific date and he gave all the signals that he really liked being with you. Either he is afraid to call too soon; something urgent came up in his life to upstage contacting you right now; or he might be involved with someone else and is a potential jerk. I mention both options because the truth is, you don't know for sure. Sometimes from Saturday to Tuesday seems like a long time, but on the other hand, it is not. All I know is---don't call him. Try not to think about him. Give it a week. If he waits longer than a week, you can still go out with him again, or not. You have control over this. But I'm sure your date was successful.
