DH is a wonderful, patient husband and father. He communicates well, and listens (for the most part) to what people say. His mother, on the other hand is not patient and doesn't listen. We have had boundary trampling issues in the past with our family as a whole and DS in particular. We have changed our behavior to keep minimal contact for DH and I with MIL.
DS (14) decided this summer that he would like to have a guitar. I did research and got advice from a few friends that are musicians and picked out the perfect guitar to buy for him. I planned to spend a few hundred this Christmas on an archival quality instrument that he could pass down to his children. My family is on a budget, but we have found it worthwhile to spend the money for a better product than something we could get cheaper.
Somehow, MIL found out about the guitar idea. MIL went out and bought a damaged, used guitar at a resale shop. I am absolutely speechless at this point. Do I continue with my plans to buy DS the guitar? Do I confront MIL? Do I continue to let DS spend time with her?
What would you do in my place?
