western relationship? I assume you mean western countries... since when did anyone in the West ever do that? You're kidding yourself really. It's apparent you've never been in the marriage/divorce threads on FR.
You're close -- ;-)
What I meant was that in Western countries, a man (or his family) does not just "select" a woman to marry and sh must comply. Folks generally date, fall in love etc etc.
I guess there are horrible exceptions you can point to, but I was speaking in generalities that would align to the study -- most marriages in the US are mutually agreed to.
