Dad and boyfriend problems?

So here's the story. I moved from my mom's more than 7 months ago to my dad's because she divorced my step dad. My dad has been trying to get me to live with him and I've been wanting to live with him. Then here comes this dude, the love of my life. I'm 100% sure. He takes real good care of me, stays with me if I'm alone (because my dad and step mom often leave the house without saying a word), offers to provide for me. He's not possessive or anything, he just wants me to be happy and live a good life. He understands me like no other and I've had 2 long term relationships before. So anyways, we've been together for at least 4 months. I know that seems like a short time but I hear a lot of stories where people date for two months, get married for a long time. But back to the story. We've been getting in trouble for having sleepovers at each others houses and I get in trouble for staying out really late, and not getting any jobs. I really have been trying and my boyfriend helps me. I really ruined my dad's trust though. I can't even leave my room to face him because I'm ashamed that I hurt and disappoint him like that. I mean he was the most important person in my life even though I didn't live with him for 16 or 17 years. On the other hand, I am almost 20 years old, I feel too old for curfews, and I'm having the time of my life with someone who believes in true love as much as I do. I don't know what to do about this situation. I'd like to move out because I don't like rules and to see my boyfriend everyday but I still need parent's support and love, I don't want my dad to feel bad and disappointed. It's just so stressful. And we were planning a trip to Six Flags but I don't know if I'm allowed. I'm too scared to ask my pops. I could just imagine him saying "NOO! you kidding me?!" I'm old and mature enough right? Maybe I'm not. ahh I'm torn.
