It is not a jewish concept. At least the physical part.
As every learned man knows love comes after marriage (or not). 🙂
It definitely doesn’t come beforehand.
What you think is love is actually called lust. You can like the person, be excited, about them, click with them and have mutual likes dislikes, similar personalities, that just means you are compatible, but true love comes from giving & sharing life experience, working together & overcoming hardships, etc..
