I think we are in agreement in some things, but most of us think the MILs previous financial commitment to her DD is important & should not change, period. When the OP said, her DD was planning around her sister's schedule, it became even more obvious that the MOG's opinion is insignificant. It's apparent it's about the bride's family & their schedule. To me, it's a shame that the bride or her mom appear to feel this is an "engagement issue", when in fact it's an issue the bride & her fiance created. As long as the bride puts her family first (as with her sister's schedule), & doesn't consider the groom's family schedule there will be issues. It's issues the couple are creating. The future bride & groom need to take a step back & consider both families, not just hers. At this point, it's a very one sided decision. FTR, I don't know any of these people, but from what we've been told, the bride's family seem to be making the decisions that work for their family, regardless of what works for the groom's family.
