Finding a suitable spouse

I wanted to ask this question because I need some advice. I like this pious muslimah, she is in fear of Allah and a good woman and we are both interested in each other. My dad however doesn't not approve of this what so ever and I have talked to him numerous times. He always puts himself before myself in marriage, saying things like. "If I do not know her parents, you can't haver her". And you do not know anything about relationships. I am really hurt because I like this girl we are from the same religion and he is so stuck on traditions chooses it over what the religion teaches. I have tried talking to him over and over but he doesn't listen to what I have to say and makes the same point. What do I do?
