1. Your mother directly says it is “not your house.”
That matters because it shows the ownership framing being used to shut down your input.
2. You state your investment clearly.
You say you invested over $100,000 into the house and need to know where that leaves you.
3. She dismisses that as your problem.
That is a key quote. It shows your financial/equitable-interest concern being rejected rather than addressed.
4. She still relies on you immediately after.
She needs help with phone/link/technical issues and thanks you, saying it is like a foreign language to her. That contrast is useful: your input is rejected when it concerns the house, but your help is relied on when she needs it.
