I have a FMIL who agreed to pay for the Rehearsal Dinner, which is awesome! She keeps changing her mind and lowering the amount she will contribute. It's frustrating and stressful because my FI and I would like to lock down a venue and menu. She doesn't want to do a damn thing when it comes to planning it. She wants FI and I to do ALL of the planning! Do you have any suggestions as to how to handle this?
