He disappeared after the first date. What happened?

The date happened, and further contact has not. That gap leaves the next meeting undecided; it does not tell you the exact reason or turn one evening into a verdict on either person.

If you want to meet again, a direct invitation can settle the practical question more clearly than replaying the date. If it remains unanswered, there is still no agreed next date, and your plans need not stay open for one.
