Hi, and sorry this is happening to you...
I think that you shouldn't let your dad's feelings (like anger) get in the way of Your happiness. You're an adult; you can see who you wish. And it's a great thing that you found somebody that can make you feel better.
Is moving out a possibility? Then you won't have to feel so restricted because you won't be "under daddy's roof".
Best of luck to you..
Much love..
