Should I continue to take the initiative or let nature take its course?

Don't let nature take its course. The key is to spend more time with her. It doesn't matter if you don't date alone, and don't show too much concern, but let her know that you are by her side. This should be more suitable for your personality. She may not like you very much, so she doesn't want to see you send her a message like that. Take your time. As for your foreman, you have to do something small. Ask your foreman, "They are all men. Do you like her? If so, let's argue." Then if your foreman likes her, he may be anxious, care about her, and tell her that if this girl also likes the foreman, you have no chance. If you don't like him, the foreman is probably worse than your situation, and you will have another chance. As for this girl, I don't know what kind of person she is. I guess you have to slow down. Let her discover your advantages and show it slowly.
