Scared to move in with him...

So I’ll be moving in with my boyfriend soon like in the next month or two. I was super excited but now I’m scared. I’m scared this is going to be a wrong decision. I might be making the wrong decision and I might regret it. I’ve stayed with my parents my whole life. I’m only 24. But I’m just scared y’all. Even though my parents disagree with it. Idk why I feel this way. Idk if I’m scared that we are not going to make it financially ( we do have a budget plan) or our relationship is not going to last long after that or a mix or everything...
