Unfortunately when a child picks a chosson or Kallah that doesn’t necessarily mean WE are picking OUR mechutanim. But we can only argue and/or negotiate so far without tipping the apple cart and causing issues for the couple. Most of us do what we have to in order to make sure it is smooth sailing for the couple. If you push too far or say “no” too much you fear that you will break the shidduch. You have to know who you are dealing with, and obviously “always here” was in a difficult situation that she felt she couldn’t maneuver out of without causing problems for the couple.
No one wants to be the one that puts her foot down and breaks the shidduch. It is a very difficult ballet and balancing act to maneuver through till after the chupah and sheva brochos when you are done with the mechutanim. In many cases you are walking on egg shells. Some times it runs very smoothly and you are both on the same page, but in some cases it can be a real challenge.
