I agree with knaidllach that love comes after marriage. It says Breishis 24,67 Yitzchok brough Rivkah to the tent of his mother Sara, he took Rivkah as his wife and came to love her thereby consoling himself after his mother.
The Ohr Hachaim Hakadosh gives two reasons why Yaakov Avinu loved Rachel, one, not because of her beauty but being his besherte, two. beauty was against resisting yetzer hara by not desiring someone beautiful. He saw her as a cheftzei shel mitzva.
