Hi W

As I see it, you aren’t dating you’re just friends.It sounds like you may have feelings that you haven’t discussed with your coworker.

As you are both just friends, she is free to see whoever she chooses whenever she chooses. She can’t wait around after you who hasn’t made a move forever. She has made her feelings known to you, you have repeatedly rejected her and set a boundary of friendship.

I would suggest actually dating her since you have developed some feelings for her. If you stop messing around with her feelings and show some commitment, she could be a great partner.
