You have annoyed her. The thing to do here is to present her with flowers and a box of chocolates.
Dude, when you cook a steak do you throw it in the pan and then take it right out and eat it at the first sound of a sizzle? Of course not. You make sure it’s properly cooked first.
Seduction is an art form. Your overly direct and premature approach did you in. Plus you come across to her as eager and “all-in”. In addition, you are way too invested in this woman. She’s living in your head rent-free. I recommend that you evict her and work on a more balanced, deliberate handling of the next one.
And stay away from coworkers and supervisors. Once you offend them they will do everything in their power to undermine your position in the company. They do it 90% subconsciously and that’s why they’re so ruthless when it comes to this.
Get over your obsession and consider her a rung on the ladder to your success with women that you stepped on and passed.
These blind obsessions with women always lead to serious consequences.
