salamu alaykum Dear sister, may Allah guide you to the true path of slam. I just want say I am a Somali man and some of my aunties and cousins married European men for the past 60 yrs, so if someone told you that it never happen befor it's not true. Second, your cultures are different and you need to work more harder than those who share same culture. third, if you are really good muslim, then Allah would never let you down. I think marige and choosing a spouse is the most seriose business that one can egage so, choose for your spouse his knowledge and practices of his deen. may allah guide you.
