I'm really not. Trust me. Don't be a dick, just do whatever you have to in your brain to get yourself to stop giving her special attention. You have to get your eyes to do the right thing. Idk it's hard to explain...
Like if there was a big wolf standing off against you, you don't try to hide your fear, it will still sense it on you. You have to convince yourself against your better judgement that it isn't something to fear in the first place, even if it is indeed scary af and can rip you to pieces. If you can do that, it will feel doubt bc it senses no fear.
If she can feel like she's not being obsessed over, she won't feel threatened/creeped on, and it will make you seem confident. And no matter how well you guage your interactions with her to not be creepy, your eyes will give everything away. The best way to get yourself to treat her like anybody else is to just accept that it's over and you're never going to get her because it is plausible right? You're not going to convince yourself that she's not hot. You're not going to convince yourself that you're suddenly James Bond. So this is what you have to tell your brain to get the desired outcome.
If this wasn't a workplace you could be more forward. Like in a club you can send her glances. But women's anti-creep defenses are on full alert in the workplace. You have to intrigue her like this.
