Agree, but how will you pay? Can you afford to transfer? Transfers get very little funding, if any. You need to make a financial plan. I’m assuming they will not be providing ANY support when you transfer. You need their FAFSA information until you graduate, if you don’t have funding on your own.
So, you need to make a plan on how you will pay for the next couple of years.
Also, you need to find counseling services on your current campus. Let them know how much you really need them to be confidential. It’s part of their ethics and training, but you need to reiterate it.
Maybe they can even help you find funding to transfer to your instate college without your Dad’s financial support.
If not, have that conversation with your parents with another trusting adult is present. If your Dad originally told you that you could transfer, and now he’s backing out, make sure you reiterate it and make sure your adult hears it.
You signed in good faith.
A deception is a deception. Trust is something that shouldn’t be broken. If your father has broken it, he’ll never regain your trust and that’s just sad.
