YTA. She pays rent on time. What bother is it to you.

My own father acted the same as you. I quit my (in his words ) “well paying job” to volunteer for a government agency across the country in the job I wanted. He didn’t talk to me for a full year.

Guess what happened in that year ? I volunteered. Got good paying jobs. And made a life for myself. What did my older siblings not do ? Any of that. They still ask my father for money and I have yet to … even though I work for the government and we have random shutdowns where we don’t get paid for months at a time ( thanks trump).

Current day : my father brags about me and the work I do. Does he brag about my siblings who stuck close to home and in the jobs he thought were right for them ? Hell no.

Moral of the story : support your daughter and let her do what she wants. If she falls. She falls. But don’t be an asshole and discourage her because her job doesn’t seem worthy to you.
