I thought you were supposed to be Torah observant. Here I am, someone who doesn't hold to that general approach to Torah having to argue Torah application with you.
Numbers 30:3-5 says that the father has the authority to nullify the vow of the daughter on the day that he hears of it. Marriage being a covenant falls under the category of vows.
This only applies to the daughter in her her father's house in her youth. It doesn't apply to widowed or divorced women (verse 9), or apparently an older unmarried daughter living independently.
It wouldn't have applied in the case of you and
@windblown, though I agree it was considerate to request her father's blessing.
Deuteronomy 7:1-3 prohibited the Israelites from marrying the various Canaanite people. Among other things God said "You shall not give your daughter to their son". This assumes the father's authority to give or refuse to give his daughter in marriage.
The Israelite father did have the authority to tell his daughter "No, you may not marry Bob the Jebusite down the street".
Exodus 22:16-17 also makes it clear that the father has this authority over the unmarried daughter living in his house. He can refuse to give her even after a consensual one flesh sexual union has occurred.
The authority of a husband over his wife or wives is greater than that of a father over his unmarried daughters, but that father authority is still real.
Once the father gives the daughter (or fails to nullify on the day her hears of it) he no longer has the authority. The authority is permanently transferred.
King Saul had no authority (as father or king) to nullify the marriage of David and Michal after the fact.
