Your family can help pay for your future. They can’t make the choices inside it for you.

Money and authority are not the same thing, although they get tangled together very easily. People who contribute often feel entitled to decide, and you can be genuinely grateful and still be the person who has to live in the result. Gratitude is owed, and obedience is a separate question.

If there is pressure on you, separate the two: thank them properly for the help and then say what you are choosing. Expect them to be disappointed for a while and let that be survivable. Where the money comes with conditions, get those said out loud now rather than later.
