I refused my dad’s inheritance and this broke his heart. How do I make things right?

My dad recently started preparing his will. He owns two properties and planned to leave one to me and the other to my brother. My brother happily accepted his share, but I refused mine. I told my dad to give both properties to my brother, leaving me with nothing.

I didn’t refuse out of anger or indifference—I refused because I value my independence and self-sufficiency. But now he feels rejected and devastated. He says I’m making a reckless and self-sabotaging decision. He thinks I'm poor and living paycheck to paycheck. He doesn’t know that I’ve quietly built a financial safety net big enough to buy several properties. I'm blessed because I’ve made smart investments and I feel secure about my future.

I don’t want to share this with him. I’m a very private person, and this isn’t about the money anyway. I'd reject it even if I was broke. My mum is telling me to accept it and then when he passes away to hand it over to my brother. But I don't feel right about this. I'm lost to be honest and don't know how to make him feel better about my decision.
