ok…. having red many shidduchim myself, i see this situation in a bit of a different light. apparently the person you were speaking to either decided that for whatever reason you were not a match for the person he/she originally thought you were suited for, or he/she red the shidduch and got a no from the other end. the person suggesting the shidduch did not want to hurt you so they just beat around the bush.
What they dont know is that this can actually cause more hurt than just being honest. It’s best to be honest with someone and say you realized they were not suited for each other than to keep the person wondering what happened. Communication! It’s not just for marriage. it’s for everyday conversations! dont just avoid getting back to someone. be a mentch! and be professional and give the person the decency of a response – even if it is not pleasant. Learn how to say it in a tactful way.
