Genesis 30

There's no no reason to think that Rachel even liked Jacob, much less loved him.

Of course we're told that Jacob was in love with her, a fact of which Laban took advantage. But what does the Bible actually say about Rachel? She whined and complained. She bossed him around. She was jealous, not only of her sister but also of their servants.

We in the modern West have so identified love and marriage that it's hard to remember that for most of humanity they simply haven't gone together. For better or worse, children married who their parents told them to. I don't doubt this was the case with Rachel.
