My daughter way back when was in shiduchim she casually and foolishly said that she wouldn’t “shtelzich” on such an issue. I very sweetly turned to her and made it very clear to her that “this isn’t hers to give away”.
We have only one daughter and I wasn’t going to allow my daughter to steal my husband’s right to walk her down to the chupah. It wasn’t up to her to negotiate this. And I certainly worked hard enough to raise my boys that I wasn’t giving that away either. Turns out if worked out well because OUR mechutanim felt the same way.
