Need advice: Parents refusing my choice of a future revert husband

Assalamu alaykum, I need some urgent advice, opinions, and Islamic guidance please. I’m 20 and born Muslim, he’s 21 and hasn’t converted yet (he’s worried he’ll struggle with praying and fasting, and I’ve told him I’ll support and help him). We’re at the same university - I’d known of him for a year but only started talking in September, and from the start it felt like I’d met my soulmate. He’s kind, respectful, has a good sense of humour, and-importantly-he’s learned a lot about Islam on his own. I did basic Islamic studies for years, and his independent knowledge is what brought us together. Over time we grew close, and I made clear I don’t want a haram relationship. We agreed that if we were ready we’d do the nikah, which we tried to arrange, but my parents became a major obstacle. My parents are typical brown parents-overprotective and wanting to decide my future. When I told them, they reacted very strongly. They’ve said they’ll cut contact, wish our marriage to fail, and that I’ll regret it and lose respect if I don’t end things. I’m an only child and their threats to withdraw contact are terrifying. I’ve tried to explain that his character and faith potential matter more to me than reputation or cultural expectations. I didn’t expect them to react this badly. He’s sincere and doesn’t want to let me go, and I don’t want to hurt him. I honestly feel marrying a revert could help both of us grow in deen. I’m aware Islam honours parents and we’re taught to treat them well, but I’m really torn. I don’t know if waiting will soften them or if this isn’t meant to be. I’d appreciate any practical advice and Islamic perspectives on balancing obedience to parents with my right to marry someone good who’s willing to embrace Islam. Jazakum Allah khair.
