It's not easy to find a spouse these days. Nevertheless, the best way to go about it is through your family and friends, most Somalis I know do that, these apps like Muzmatch are a waste of time and full of weirdos.
There is a problem with Somalis in the west getting married definitely, especially in meeting eachother. Somali girls where though stay away from guys, now they are told go get your self a spouse, which is unrealistic.
Lastly, this goes for the girls, if a good Somali guy approaches you for marriage, don't reject them for superficial things like hes is not 6'5 or won't give you 30k meher.
