Diamond chaos

After hearing about aromanticism I agreed with a lot of things that they mentioned and I’m just questioning myself I’ve had a couple crushes on people but they only lasted a few days at most and when I think about them I can’t think of a reason I had a crush on them. I’ve also got friends that are in a relationship and it doesn’t disgust me or anything thing but I don’t quite get what it’s about. I don’t know if I’m just thinking too much about it or if I am aromatic I’m just not sure and need to ask someone who knows more about this kind of thing as I know very little about this kind of thing.
