Right. I've only gotten that line once, and I did NOT call him. In my experience, when a man enjoys himself on a date or really wants to see you again, he'll try to set the next date while still on the first or he'll definitely call 3-5 days later to say that he enjoyed himself and propose another meeting.
Our jobs as women are not to court them...they are to pursue and court us...our jobs in the dating phase are simply to be beautiful, charming, and engaging and give him just cause for calling and courting us.
Men are more simple than that. If he wants to talk/connect/go out, he'll call...if he doesn't, he won't.
