<p>The double majoring idea is a good one. However, you need to prepare for the very real possibility that he will, in fact, cut you off, be it financially or both financially and emotionally. He’s told you what he’s planning, and you need to believe him.</p>
<p>You might want to start figuring out some ways to disentangle yourself from your parents financially before you graduate if at all possible, or else you face having their financial support be a source of control and manipulation. </p>
<p>Get a campus job. Work over the summers. Get yourself a reliable used car in your name only if you don’t have transportation already (obviously this doesn’t apply to a place like NYC with large-scale public transport). Get your own phone. Shutting down your phone will probably be the first thing your dad tries to do to regain control if you make a decision he doesn’t agree with. Go to your financial aid office, explain your circumstances, and find out about taking out student loans in your name only to continue your education should your dad stop paying your tuition.</p>
<p>Get your stuff out of their house, incrementally if you don’t want to arouse suspicion, and either keep it with you or put it in storage. He might trash your things at home if he gets angry enough, so make sure anything of value is with you.</p>
<p>I’m nervous for you about living at home during the summers in case he really does throw you out. You need to have a housing backup plan, although preferably you’ll be spending your summers working and can get campus housing. </p>
<p>Finally, stop giving your dad information. Don’t volunteer it. If he asks for it, give him the minimum that will satisfy him and continue on your way.</p>
<p>If you don’t think that this is a cultural thing (not sure of your culture) and you think it’s just a straight up A hole thing, check out [Daughters</a> of Narcissistic Mothers](<a href=“http://www.daughtersofnarcissisticmothers.com%5DDaughters”>http://www.daughtersofnarcissisticmothers.com). Applies to sons and fathers, too.</p>
<p>You are more than an extension of your father and of your family. Just get your ducks in a row and make sure that you’re ready to be independent sooner than you planned. Sorry you’re going through this.</p>
