Do not come out unless you are safe. Do what is safe for you and will make you feel comfortable (ex: cutting your hair, using preferred names around safe people, dressing more masculine), but unless you're in a safe situation it isn't worth it to come out until you can get away from the unsafe people around you. 

As for your boyfriend, nothing justifies his actions and nothing justifies staying with him. If he's acting like this nothing is stopping him from escalating his treatment. Leave him ASAP and don't look back. 

break up with the bf !  also just be honset I'm not trans but I have like 7 friends who are they all came out to me first and then they  told their parents just be honset and if you get stuck in a bible I would say maybe this : Mom, Dad, there's something important I want to tell you. I've been thinking about this for a long time, and I'm transgender. I know this might be hard to understand, especially because of our faith, but this is something real to me. I'm still the same person you've always known, and I still love you. I'm not asking you to understand everything right away. I just hope you can listen to me and try to understand who I am. I really need your love and support right now. ( my friend said that to the VERY Catholic family) idk you do u ok
