[19F] Is it weird that a guy [20M] with a girlfriend watches my story every day?

Okay I might sound a little crazy but I just want some outside opinions. I’ve always been the type of person who holds onto things longer than most people. Like, I feel things really deeply and small moments end up meaning a lot to me, especially because I haven’t had a lot of relationships. So back in elementary school, I had my first kiss with this guy. It was his first kiss too. We were best friends, and we had that whole “we used to hate each other, then got close” kind of thing. One night we ended up kissing. Obviously we were kids, so it wasn’t anything serious, but it still stuck with me. I’ll be honest too — I was going through a lot at home at the time, and I definitely said/did some weird things as a kid. So part of me has always worried he probably thinks I’m crazy or something. Anyway, he’s kind of popped in and out of my life over the years. We talked again briefly in high school just to catch up. Now we’re both out of high school (I’m 19, he’s 20), and recently I’ve noticed he watches my Snapchat story literally every day. Like… he never misses it. Most of the time he’s one of the first people to view it too. The timing is sometimes random, but he still always watches. Here’s the part that confuses me: he has a girlfriend. I’ve seen her on his Instagram. So I’m just sitting here like… is this kind of weird or am I reading too much into it? If I had a boyfriend, I personally wouldn’t be checking another guy’s story every single day — especially someone I had history with, let alone my first kiss. That’s why it stands out to me. He doesn’t message me or anything, just watches everything I post. Do you think this actually means anything? Like maybe he wants to reach out but doesn’t because he has a girlfriend? Or is this just normal and I’m thinking too deeply about it? Be honest 😭
