Do levels matter?

I recently re connected with a guy I used to talk to about 2 years ago, things didn’t work out then but we were 15, were both now 17 & i really like him, he asked me out but I guess teenage insecurities are starting to mess with me because I feel almost as if I’m not on his level, I don’t find myself ugly I just, don’t wanna end up looking stupid as if something doesn’t workout I don’t want the “did u really think a guy like him would like you” idk, maybe it’s my cycle, maybe it shouldn’t/doesn’t matter. (I didn’t have any close up pictures of him 🤷🏼‍♀️)
