I think a lot of these categories kind-of overlap in various ways all the time. Except maybe not the fall in love part, at least not for me.
Maybe I'm like Sleepy's "muddled" friend, I don't know. But I can pretty much end up being at least somewhat attracted to almost anyone that I spend enough time with . . . Since I'm straight for most general purposes, in the case of girls that means finding them aesthetically good-looking and in the case of guys that means something that could feel more like a crush, even if it usually isn't all-out sexual attraction. Once I get to know a person emotionally/mentally/whatever, I usually end up recognizing more of their physical beauty too. Because pretty much everyone is beautiful in some way.
I have had a handful of male friends who it seems like I could only ever just be friends with them. But even them, I can very much appreciate the way they look and things like that. Not that there is sexual tension necessarily.
You know, this topic has been on my mind recently. Cause I want to hang out more with this married guy friend of mine. But I feel like he feels a little bit uncomfortable about it. I do have a crush on him, but I'm in a relationship too. I have no intentions of that sort. I just want to spend time with him cause he's an awesome person. But I feel like the fact we are both in relationships seems to be getting in the way. And it's frustrating.
