If dad doesn't like my boyfriend, should I talk to him?

I suggest you don't say it, then he will find your father difficult to get along with, deliberately make things difficult for him, and will gradually dislike your father. If you are going to get married, your father's conditions will become what he thinks is difficult. As long as you like it, don't care whether he likes it or not. The most important thing is to try to make your father accept this fact. If you don't like it then, there is no reason to stop you.
