Hi OP,
I am very sorry to hear that you, your partner and your children have experienced such negativity.
I am the daughter of an interracial marriage. The same as you guys, My Mum is white and my Dad was Black/Jamaican.
We were a happy and loving family growing up, I couldn't have asked for better parents.
We lived in a predominantly white town where we were the only black / interracial family for miles. We were very lucky as children that we didn't experience any major racist incidents.
However my parents sadly suffered an awful lot of racism when they met and long afterwards in the 60's and 70's.
I can remember my Mum saying that local people would often make racist comments and say the marriage wouldn't last. They stayed together for better or worse for 45 years, long after many of the racist scum had gone through divorces.
Both of my parents worked incredibly hard to give us everything we needed. They scrimped and saved to make sure we had a nice home in a good area and myself and my siblings will be forever grateful to them for that.
In particular, I couldn't be prouder of my Jamaican Dad, he was my hero, a man who worked from the moment he arrived in Britain until the moment ill health forced him to retire. He faced a huge amount of racism for daring to be a Black man in a largely white town. He looked 'scary' to many white people until they took the time to get to know him. For those who didn't, it was their loss.
I am very proud of my dual Jamaican and British heritage, I feel it gives me a unique awareness of what it feels like to have a foot in both camps in some ways. I do consider myself to be Black British and I would not change a single thing about my heritage given the chance.
The main ingredient for a family is love and you and your partner are providing this for your family.
In 2020 it still amazes me that racism exists to the extent it does especially somewhere as multicultural as London. It is very sad that you have experienced vile comments from young people too. When will the cycle ever end?
The racist comments hurt, but they usually stem from total ignorance. I'm sure you teach your children to be proud of their dual heritage. They should grow up with confidence about their family history and pride.
Don't let any negativity about your relationship or your children's dual heritage spoil your happy family.
Apologies for writing so much, I just relate to you and wanted to offer my support.
I wish you and your family great happiness for the future x
