Late reply but something similar happened to me with the best friend friend thing. I had crush on my "best friend"(well not anymore) and I told some of my friends that I had a crush on him, I told my friends that I had a crush on him cause I thought I could trust on them but I guess not. One of my friends told him and I don't even know why they did,then he started to ignore me and he started to talk behind my back. Now, we don't even talk and till the point I was so pissed ,I wrote a story about it.

Hahaha you might thinking you're subtle when you're not too other people lool. I'd say if you ever feel like the time is right and you have the strength to combine on. Tell tale signs hmmm. That's a good one err, weirdly enough I have a really bad habit of making people think I like them when I don't by just being touchy feely and friendly to everyone no matter who. So because I treat everyone in that way, it's easy to realise that there's nothing suspicious about the way I interact with certain people after a while. This is why I've never been called out for liking someone ever because I've always been as cool as a cucumber when it comes to communication. That in mind, when I do like someone, I treat them a bit more softly and gently - ask them more questions in an effort to get to know them better, make sure they're comfortable, less flirty (I take them seriously), sweaty hands, irregular heartbeat, laughing hard at their jokes, praising them regularly, slow seductive gazes, putting a visible effort in to look good, second guessing myself a bit more, light heartedly teasing them, thinking before I speak (want to come across a good individual so the brain must be censored sometimes
