Do we need her father’s blessing?

Question:

I bring you greetings,

Please, sir, I have a pressing question that demands an urgent answer.

I proposed to a girl and she accepted after praying about it. We both belong to one group in our church and according to the ethics of the group, every member of the group must attend an interview where renowned counselors, all elders of the church, question you about your conviction.  After the interview, they advised us to go ahead with our wedding plans.

In my county's custom, marriage is a process so the next thing I did was to go and meet her parents with members of my family and one member of our church. Before we went there, I let her father know in advance that I will discuss something important with him and we booked a date. We met him on the said date and told him our mission and he said OK, he has heard us and that he will discuss it with his daughter and later get back to us.

Two weeks later, he called me and said he would like to see me and my brother alone. He said my brother would stand in place of my father because my father is deceased. He met us that day and said that there is something he won't tolerate and that is to try to convert his wife from paganism to Christianity. He won't like anything that will bring division between him and his wife. I said OK. You are the head of the family and you don't want division. I will not preach to your wife alone. Anytime I want to preach, I will preach to both of you so that I won't cause division between the two of you. He said OK that if I maintain this boundary, there will be no problem. But he still wanted to meet his daughter and ask her some questions.

After another two weeks, he called me and told me that they have accepted me. The only thing I should do now is to allow his daughter to finish school or to at least reach the final year before our wedding, and I agreed to that. When the daughter reached her final year, I approached him again to remind him of his promise. He said his daughter didn't inform him properly the first day we came to his house. Because of that, I should go and find another person to marry. I asked him if I have ever offended him, and he said no. Then I asked him why are you doing this? Your daughter didn't inform you properly, yet you welcomed us, accepted what we brought, told us that you will get back to us which you later did, and told me to wait till she reach her final year, which I did, only to come back now to tell me that I should go and look for another person because she didn't inform you properly? And he said that is it.

So my question now is, must we receive his blessings when he is tyrannically abusing his fatherhood authority? As it stands now, I want to go on and start planning my wedding.

I met my local priest and told him. He said I must wait for his blessings and that, even though he is a pagan, his blessings are essential to our marriage. Since he said that, I have been thinking, can God be so insensitive to the feelings of His children that He will allow an unbeliever to manipulate them any way he wants because of tradition? I know my God is not a God of injustice. But, please, I still need your advice. What should I do?
