Why Do I Feel Like This

Ladies please hear me out, this coming Saturday will be the first time I meet my boyfriend. We have been going out for a year and 6 months today. I'm super excited to see him don't get me wrong but there's something in me that's indecisive about it like if I'm scared to meet him or nervous of some sort. I love him very very much and I plan to marry him when I finish college but idk why I'm feeling this way. Is it just jitters?? Am I just over thinking?? I really do wanna see him I just don't know why I'm feeling this way. Please help me understand why I'm feeling this way
