Title is pretty self-explanatory, but for a few more details: I have feelings for my best friend and have for just under a year. She and her ex-boyfriend were together for about two and a half years and I promised myself I wouldn't interfere with her relationship as long as she was happy. Since they're no longer together (they broke up over differing life goals), I figure I should admit I realized I have feelings for her. A couple of small notes:

• She has always told me that she prefers to date men that are already her friends beforehand.

• She got over her ex in record time. It was less than a week, which I'm not sure is good or bad news.

• She's recently been flirting with me a lot more, talking about what kind of guy she looks for (which makes mention of my occupation), saying I'm on a "special list" but never expounding on that, she started opening up about how unsatisfying her sex life was with her last boyfriend.

• But then she's also giving me mixed signals, like telling mutual friends (when I was in the room) that she usually doesn't date anyone for six months after a break-up.

• They broke up at the very end of last month.

Am I way overthinking this? I feel like the longer I talk to her without telling her how I feel, the more I am lying to her. At this point, I feel confident that, even if she doesn't reciprocate my feelings, we'd still stay friends, so I have nothing to lose. But I'd still rather talk to her about it at a time that would most likely lead to success with this.

So what's the standard time? Or even just the best time?
