<human>: Can you condense the text into three sentences or less?

My boyfriend and I have been together for nearly three years and I am absolutely crazy about him. Unfortunately, we are long-distance right now (North America - Europe) but we have had lots of visits, he spent the summer with me and we had a really amazing time together. I'm trying my best to move abroad to be with him, but right now it is a waiting game. We are trying to see each other every three/four months, and the way that it worked out with my job made visiting him over Christmas the best time for me to take off work. 

I am going home for Thanksgiving in a few weeks, and I know that I have to tell my dad that I won't be spending the holidays with him and will instead be with my boyfriend. My dad is very family-focused, and he is very much a Christmas guy. He isn't religious or anything, but I guess since it is the "big" holiday, he likes our whole family to be together (including cousins, aunts and uncles, etc.) 

He doesn't like my boyfriend, but it is an unfair opinion because he has only met him once. Even though my boyfriend spent the whole summer with me, my dad refused to talk to me, wouldn't let us visit and when I did stop in to wish him a Happy Birthday, he completely shut me down and ignored me. I assume that his reason for not liking my boyfriend is that he is afraid of me moving abroad, because he truly has no other reason not to like him.

I don't know how to tell my dad that I won't be home for Christmas, because I know he will be absolutely furious. He definitely has anger issues and often says horrible things, then tries to repent later. An example was the time I missed a flight home and he told me that "If I knew you would cause me this much trouble, I never would have wanted you". I expect that telling him about my trip to see my boyfriend will result in something similar and will lead to even more distance between us. 

Does anyone have any advice on how to approach this topic and how to respond to the probable outburst of mean comments?
<bot>: I have to tell my dad that I won't be spending the holidays with him. He will be super angry, and I don't know how to approach the topic or respond/prepare for his angry outburst.
