Hi! Do what feels right for you! Your dad is right, his house, his rules. I lived with my parents up until I got married (I lived on my own twice before), and I still had a curfew too. If you do move out, I don't believe that you should move in with your boyfriend. Move in with a close girl friend or a cousin, sister, etc. You need a time to just be truly independent, and not dependent on a man. You don't want to get into a pattern of using your romantic relationships as an escape from a parent or parents. Also, I don't believe in 'shacking up'. It may work out fine, but you set yourself up for major stress if you both break up, or being afraid to break up with your boyfriend because you are living with him, and you don't want to upset your housing situation.
You could also just put up with your dad. A 10 pm curfew might be a bit early, but it's not terrible. At a certain time, he might want to be able to go to sleep in peace, and not have to be concerned with when you're getting home or he might not want to be awaken by you coming into the house at 12:30 am. Also, your dad might have good reason for not wanting you to date your much older boyfriend. Take some time out to try to see things from your dad's viewpoint. That is how you truly know that you're becoming a mature adult. The plus of staying with your dad is that you don't have to concern yourself with bills, rent, etc. You would be able to save up your money. It's a BIG responsibility to live on your own.
So yeah, it's really up to you on what decision to make. Just pray about it, and really take time out to see what the pros and cons are of each decision. Hope everything works out!
