Even without tnoyim breaking an engagement (c’v) is a humongous deal, and a shaila must be asked FIRST
Why is it a humongous deal? Assuming that they don’t go ahead and completely trash the other party, why is it such a big deal?
In addition, let me ask this question — if a shaila is asked, and the rav says no, you really think the person must remained married to a person that they don’t want to be married to?
