Assalamualaikum - Parents Changed Their Mind About Me Studying Abroad, What Now?

Assalamualaikum. My dad used to be all for me travelling and studying abroad. Even when my mom suggested I study back in our home country, my dad would get excited about the abroad plan and they’d talk it over. He also used to say those were just options and that going abroad was still possible. I began preparing for the IELTS as the first step. I went to book a test, and suddenly my dad started crying, saying he couldn’t imagine life without me and then told me I’m not allowed to go. I was shocked - we argued. I stayed respectful but I dissociated a bit while he yelled and cursed. I reminded him he’d approved it many times before; I’d asked him over and over and he listened to my dreams and plans and supported me. He said, “I thought you would fail like always.” It’s true I overthink and I’ve been anxious about university because here we don’t get full scholarships for immigrants and the costs are high. I always worried and discussed options by myself until my parents banned me from talking about it. Then this new place came up and it seemed perfect - it matched my goals and even my parents’ interests. My research went well. Before deciding I thought about small practical things, like how I’d manage hygiene, how often we could visit, and I checked myself emotionally. I finally decided yes, I’m doing this. I emailed, wrote a personal statement, gathered materials for the admission test, and asked my school for my diploma. When things got real, my dad suddenly woke up and started ranting that no one will marry me and other random, immature things. My question is: what’s the Islamic perspective on continuing to try for something like this if it’s allowed? Is a man allowed to take back his word, especially after he had encouraged me for years and I trusted his support? I’m confused and hurt and would appreciate advice from people who know the deen and have gone through similar family situations. JazakAllahu khair.
