Originally, they both seemed ok with it, but it was obvious to outsiders that they were being pushed together. They are still together (4+ years) so we'll see, but we all felt they were railroaded into it because the brothers and their parents just wanted to get both of them "settled".
I have seen this numerous times if people have been dating awhile and seem to be "serious" then JWs will pressure them to get married even if they are having doubts. Or JWs will say that only "serious couples" can do certain things like sit together at meetings or publicly show affection. This is done to apply pressure to the couple to get engaged. I think JWs don't want people to court to long for fear that they may have sex before marriage. However, they are doing more harm by ruining people's reputation simply because they decide that a relationship is not going to work. In the org you could be a virgin and still have bad reputation because "you're not serious about getting married."
