I agree with those who said that your friend had a plenty of time to get to know her fiance before the actual marriage, it's called the engagement phase "khotooba" and 7 months are more than enough for them to decide whether they're good for each other or not. But the question is: is your friend unhappily married?

As for the divorce rate, just for your information, people who getting married after a long relationship end up getting divorced more than those of arranged marriage. That is because they have high expectations but they somewhat get disappointed by their partner

And speaking of feeling like raped, this feeling occurs to almost every girl even those who got married to guys they love for ten years. Every girl I know who got married told me about that feeling, and guess what most of them fell in love before marriage.. it's normal to be scared

So if you may please stop making assumptions about things you are not familiar with, love before marriage is not the key for a happily ever after ending for all people, because most people are bad when it comes to making choices
