Honestly in this situation I’d probably just stop putting the effort into reaching out to her, visiting her, etc. As long as you can financially support yourself, it doesn’t matter what she’ll think. It sounds like she already is cutting you off, so I would just let her and ignore her
it depends, do you want to be no contact with her ever again? if you don’t want to, i’d say just go for it. if not you could just stop reaching out and let it dwindle on its own. i had a similar situation and moving across country for college completely changed the relationship over time
The only thing is I would only go complete NC only if you will never need her financial help again and you’re okay with that. In your situation, considering that she doesn’t reach out to you anyway, it wouldn’t be much different in practice, so personally I’d only go NC if she flips and decides to come back into your life to make you miserable
