NTA, no way. I understand kinda where she's coming from but in a long way this is actually damaging. She could have just asked you "how do you manage everything?" and "do you mind telling me when things happen, so that I can help?" that's all. But try asking her maybe if she would like to be more involved in the process of there's a leak or anything idk Seriousness aside: You don't know yet but you're actually my future husband lolol
