Poor village workers had to work physically and strength mattered a lot. Also, you paid taxes per household making it very hard for single women to make it. E.g. girl has to marry cause living without man is super hard.
You dated two weeks at 15 and then announced marriage and then it was for live.
And that somehow precludes marrying for love?.. You are a village girl, you've been around the village, you know all the boys you age. You marry the one you like. Love.
I am not denying that pre-arranged marriages are a thing, and that they played a more prominent role in the past, but to say that genuine love played no part in the match making process until 200 years ago, like the OP suggested, is an exaggeration.
Love is a part of human evolutionary toolbox, it's been around for a while. Accordingly, the subject of love, and marrying for love, comes up in literary works since the start of recorded history.
