I moved into the house that my partner and his ex-wife bought together. They had broken up before we met, so there's no issue there. She has moved out, and they have equal custody, so the kids go between the houses week in and week out. I get along with them very well. Since I moved in, we started working on the house and changed pretty much everything. Recently, we totally refurbished the bathroom, which was the last remaining room that hadn't changed since his ex lived here.
Now, AIBU... One of the kids keeps filming and taking photos and sends them to the ex so she can see what we have done to the place. Almost every little change is reported to her mother. I find it very invasive and nosy. I know it was her house before, but she shouldn't ask the kids about the updates (I assume she does, as she is a very nosy person). Should I leave it or address it with DSD?
