This stems from enormous value that Judaism places on family and family life.Furthermore, Halachah prohibits pre-marital sex and any intimate contact between unmarried couples.
Others find much value in “casual” dating even if marriage is far from their mind.
I would draw the line on casual dating if there is no possibility of eventually marrying the other person.
Thus any relationship that is forbidden by Halachah (Jewish law) should never be allowed even in a casual context.
For those who adhere to these laws, a prolonged period of dating can be difficult.
Even couples who are more lax in these areas of Halachah still understand the high priority that Judaism places on marriage and family.
