MM:
Sorry to write this, but you did NOT bring down any sources claiming that “Tnayim” have any halachic ramifications. You brought a story that shows that breaking an engagement causes a lot of embarrassment, and that maybe one should be put into cherein (which was argued by Wolfishmusings) but never did I see any place or halachic reference that you brought down that stated that “Tnayim” have ANY halachic ramifications.
