OK people I stuffed this question up. Yup I know I am dumb as women have always made sure I know it! So no need to comment anymore because I have just given up on this woman so please don't comment.
I have worded this question wrong and it does not say what I was trying to ask. I will be disvowing it but I have to wait 24 hours. How depressing to have to wait that long with this shit question linked to my account. Fucken hek!
I don't recommend the secret admirer confessing his love route at all. If she says "no", it's like the worst below imaginable, and the odds of her saying "no" also go up when you lay it on so heavy by saying like, "I always liked you."
Like Squidward's advice (which I just wanted to kind of echo to reinforce the message), you can just do something like ask her out. Make it easy. Make it light, like you're just casually asking a girl out. And then see what happens from there if she says "yes". Even on the date, don't like say you always liked her. That's the kind of thing you might share when you two are a real item.
I tend not to tell a girl i have a crush on her. Usually i just try to figure out if the feelings seem mutal if they don't i don't bother. From my experience the reason they call it a crush is because if you tell them you get crushed.
