Girlfriend different race, family not happy. How you all handle?

Been through exactly this, now married 6 years, two kids, alhamdulillah. Real talk: the conversion is not a paperwork thing, it changes your identity, your name, sometimes your relationship with your own parents, and how you raise kids. Be very honest with yourself whether you are doing it for faith or just to marry her, because that matters long term. On the family side, give them time, don't force. My parents took almost 2 years to warm up, first Chinese New Year was awkward, first Raya even more. What worked was small consistent contact, bringing her to family dinners without pressure, letting them see she's a good person, not "the Malay girl". Love is not enough alone, you both need patience, thick skin, and a united front. It gets better, but it takes years, not months.
