Any Advice?

So, I might be over thinking this because I kind of do that a lot, but recently I’ve been feeling a bit neglected by my best friend. She’s a super sweet person and didn’t do anything wrong, (and I’m pretty sensitive so tbh it’s probably nothing but I figured I’d ask anyway) but I’m a bit worried I did something wrong without knowing it, and she isn’t telling me. The thing is, when you do something to upset her, she usually doesn’t tell you because she doesn’t want to sound rude, which is understandable, but it’s also can mean she’s holding a weight of something you did with her without telling anyone, which is also a bit worrying. She hasn’t really been texting me as much, which normally I wouldn’t think much about, but she used to text me everyday with long conversations. Now whenever I send a text and she doesn’t answer and a send a couple more, I feel like I’m spamming her and being clingy. And I don’t want to be that one friend who’s super clingy and smothering, but I don’t know what I should do. We see each other every Wednesday night, and usually every Saturday night, and we’re always super chill and fun with each other then, (which always does lift my spirits when I feel this way) so I don’t know if I should just give her some space or if I should as if I did anything (but I feel like I’d sound ive aggressive in a way if I did). Any advice would be really appreciated, thanks. :)
