I was under the impression that if one of the parties traveled quite a distance, then several dates were a given unless the person turned out to be an axe murderer or something.
I traveled from NYC to Canada to go out with a girl. The first date was on ereve shabbos. I had an awful time and couldn’t stand the girl, and I was sure she couldn’t stand me, yet I was told she was expectin my call before shabbos to arrange to meet again after shabbos. Turns out she said that because she was told “hey, he came from ny, you can’t say no after one time its not fair to him”.
Is this in fact one of the “rules” today. Its close to 20 years since I’ve dated anyone but my wife.
