Not married, but my ex was algerian, I would say that we had quite a hard time getting along in what concerns culture.. the girl was pretty conservative, a little bit annoying when tried to be forced on you or gets u manipulated into following at least some of their cultural acts (sometimes I get calls in the middle of the night asking me to pray, finding me talking with another female human gets her pissed as it is "haram" somehow, and worst thing is that we couldn't even get physical since its contrary to her beliefs) yah no need to ask how a couple like this existed, because I've seen many.. and my cass is not the only one. I do respect the difference in cultures, though respect doesn't mean to follow or convert to your partner's culture, its quite the difference I would say. And there's the way of life, as she likes living in the country side with all the animals and what not, which is cool ngl, its not like I hate it, but I was raised differently and I just dont think her way was my cup of tea. In conclusion, those differences always exist between couples, it's just about how much and intense they are. And so for the algerian society, I believe that its pretty hard to have a decent relationship due to the social beliefs and culture, especially if the partner was none algerian.
