Lol, apparently I’ve wasted a lot of time on this forum.
I'm perplexed and confused by the fact that you don't seem to regard marriage as an agreement, covenant, or vow.
I realize our modern cultural tradition of publicly exchanging vows, and signing documents with the state isn't what makes a marriage a marriage.
Isaac took Rebecca into the tent and she became his wife. That's pretty straightforward. The two shall be one flesh. What God has joined, let no man put asunder.
I also realize marriage isn't a covenant in exactly the same sense that God made a covenant with Abraham involving walking between halves of cut up animals, or exactly like that God made with Israel at Sinai.
On the other hand, the relationship between God and His people is called a covenant, and the relationship between a man and his wife or wives is said to reflect that of God and Israel, Christ and the Church.
There are two parties in a marriage, and they both have certain rights and responsibilities.
It seems undeniably obvious to me that a marriage is an agreement, and that Torah seems to indicate that virgins under their father's authority are not authorized to independently choose to enter into agreements.
I have the impression that you aren't taking the text seriously, and that your strong emotions are blinding you in regard to this issue.
Then again, some people here at biblical families have some absolutely insane ideas about sex and marriage and this is a forum where we are able to openly discuss such topics. I enjoy the fact that we have the freedom to discuss topics that are normally considered "outside the box".
