I am with a 'muslim' man and I am English. I am 25 he is 28. I use the term loosely as he is largely un practicing. E.g. He drinks, smokes, eats non halal meat etc. He has even been known to consume pork when drunk! he is british born and has lived here his whole life.
We have one dd. The only time we encountered differing views was that he wanted any children to have an Arabic name, albeit one that is very 'english' sounding. So we had Sarah, Hannah . Zack, Noah, Adam etc to choose from. And if it's a boy he would have wanted it to be circumsised. And no pork. Non halal meat is fine. She will not have to wear a head scarf and will be allowed out clubbing when 18!
He doesn't pray or attend mosque although he does fast for Ramadam.
We celebrate christmas and birthdays. (devout Muslims do not recognise birthdays with parties and presents)
And we letting dd grow to understand both religions but not practice either unless she chooses too.
We have no issues with our blended cultures. He has 3 siblings and they are all very westernized as above.
His parents are stricter and do abide by the rules of islam but it is kind of 'what they don't know don't hurt them' attitude. E.g they know they all drink but it's certainly not discussed with them. I tend not to wear low cut tops around his dad. And we don't openly admit to feeding dd non halal meat.
They never expected me to convert. Muslim men are allowed christian wives. Although we have not married. They would probably have preferred a Muslim dil deep down but have certainly never expressed this to either of them.
Not sure of what will happen when dd gets older and maybe eats a mc donalds or something and tells them!!
But so far no problems here. Although I appreciate my partner is only Muslim in name and parentage. Not in the way he lives his life day to day.
