Is it normal to hide forever with your relationship?

I don't want anything especially anyone to get in the way of my precious relationship. I guess you can say I'm overprotective of it but when you love something so dearly, its natural to wanna protect it. You're sensitive when anything that touches it could potentially hurt it. So with my relationship with my love, I prefer to stay away from everyone, just me and him, that includes family. Hes really close to his fam so I wouldn't mind spending time with them cause thats his side so he can do whatever he wants. But when it comes to my side and where I have control, I prefer to stay away. Im close to my family but still, I don't want to expose our relationship to them, especially my siblings who think they know everything. With friends and acquaintances, again on my side, I have full control and sure I'd love to introduce him to my friends and show how much he means to me but that's it. Getting close and hanging out all the time, nah, I rather just spend the time me and him alone. I think hes the same way too but less. He's introverted but his extroverted side comes out at the right time. So he's lowkey and whenever we're together, it's really lowkey. Like well just lock ourselves in the room and watch movies. We can literally do that all day every day. I honestly rather do that than go out to some big event. I wish we can just run away forever, with nothing in the way.
