Do Afghans marry Black people?

I met this Afghan boy over a year ago, we have been talking, and meeting in public. He is Muslim and I am Christian. He recently confessed that he loves me and wants to take things seriously with me and I love him too very much. Over the past year I have found Islam through him and I want to revert but I have not told him yet, and no I am not wanting to revert for him. He wants to marry me but I’m scared. I am Black and I know many cultures and many Asian cultures do not like my race and many are very family oriented. I come from a broken home with a single mother and not very much family close by. I’m scared I will be judged and not accepted by his family. He told me that his parents, especially his mum is “chill”, and would not care who he marries, as long as I give them grandchildren, and even if they object, they will not be living with us anyways he said. I really love him but I have so much fear of being hated or despised by my in laws. Anyone who is Afghan, would your parents allow you to marry a Black woman? Or someone outside of your culture even if they’re Muslim or even Christian? What views do you have on Black people and are there any Black and Afghan couples that you have seen?How strict is the Afghan culture? We are living in the west in the UK.
