Daddy issues with boyfriend

So my boyfriend and I have been dating for 2 years now. We started dating when I was 14 and he was 15. I'm 16 now and I turn 17 in 2 months.
My boyfriend and I plan on getting married on my 18th birthday (please don't hate on it or try to lecture me) 
My boyfriends family is extremely supportive and so is most of my family, except for my dad. My dad has always hated him for no reason! My boyfriend is extremely sweet and we are so in love. He disapproves of my relationship so much and I hate it. I don't want it to be like this, especially because this is the boy I'm going to marry. Does anybody have any advice for me?
**Please don't comment just to lecture me about young marriage. It's something my boyfriend and I have talked about since we were dating for 2 months and we love one another, I don't need your negative opinion.
