I agree to some extent. I believe that a person CAN change albeit maybe not right away and not a huge turnaround. Sometimes, a person may want to be spiritually higher for themselves, but don’t have the proper motivation to get there. Some people know where they are in life and where they want to go, others need a little chizuk and with the right spouse that can be achieved. All of these things need to be understood before a person gets engage.
May all be blessed and find our Zivug Hagun in the right and sweet time and may it be as soon as we like.
