<human>: Can you succinctly summarize the text in 1-3 sentences?

This is not the first time this feeling washes over me. In fact, I'm pretty sure the intensity will go away, much like it has in the past. It's not, however, a nice phase to go through, and I'd like to hear your thoughts on how to manage it.

Please excuse my English, as it's not my first language.

I met this girl about four and a half years ago, when I started college. She got me into playing music, we lived in the same residence, and she was in charge of a class given there. Over time we developed our friendship, and are now in the same band.

We are about seven people in the band. Sometimes people come and go, but all in all we're a very tight group. You could say they're my best friends.

I'm always trying to make life easier for them, I like being helpful in general, but specially with her. I have all the familiar telltales of being in love with someone, yet I don't see us dating. Firstly because it'd be very awkward with the rest of the band, and potentially disastrous to our relationship. But also because I've noticed we wouldn't be compatible as a couple.

Basically, it's like I miss her, like you would a SO, and I long to be around her and spend time together.

She's very dear to me, but she's closer friends than me, and perhaps I'm a bit jealous of that. That said, it's never been a problem when I'm not as infatuated as I am now.

This is already awkward to put into words, so I hope you get the gist of it.

These days I'm visiting family, and I've realised they have the same, or a very similar, shampoo she uses, and the smell is driving me crazy. It's what made me write this.

Would you tell them in a similar situation? Or how would you act to deal with the feeling?
<bot>: My hair now smells like my best friend's, and it made my brain go haywire. I have no idea how to approach it.
