AZOI.IS,
Glad to know that the issue turned out to not be an issue at all!
Given that your OP provided enough specific detail for the couple to potentially identify themselves, but not enough detail for us random posters to really assess the situation, is it possible that you may have been using the CR to attempt to contact this couple to find out whether they were upset by something? If so, I would be careful doing that, because it could potentially cause hurt feelings. If this wasn’t your intention, perhaps it would be a good idea to minimize or even change the specific details (e.g., location of the party, timing of the engagement, religious history of the couple, length of the shidduch, etc.) to avoid the possibility of unintentionally getting “outed.”
