When talking to my Rosh Yeshiva in regards to dating one of the many pieces of advice he gave me was the following:
“You have to think the following on your dates ‘Can you see yourself waking up next to the girl for the next 50 years’.” Meaning are you attracted to her. Attraction is relative to everyone, therefore there are no standards. However, it is definitely one of the most important aspects a boy should consider on his dates.
