How do you know if things are too intimate between you and your boss? My friends think she has a thing for me, but I never took it seriously until now

If she makes you uncomfortable, tell her.
Be tactful and kind, but honest.
If it doesn't help, there is always the labor board.
You should keep a journal. Record what your co workers have said. Record everything.
Keep your phone records too.
But, it may be as easy as a few words with her. She may just be reading you wrong.
Or...she may be a predator.

I see a raise in future, and I’m not talking about what’s in your pants

Never going to happen in my life but you might need to start looking for another job. If you do like her a relationship could work if you were not reporting to her. As it is she does not understand how to be appropriate with the power she has as your superior. Then you need to go someplace public and have a conversation and tell her how you feel and how her actions make you feel and ask what her intentions are. This could go a lot of interesting ways but a lot of them are not good. Be kind and gentle.

Put a pen inside your pants and say "ooppss my penis got fully erected after seeing u"

Get her fired. Are you serious?

If it’s making you uncomfortable then you should say something but you need to be careful about how you go about it.

Tap dat shit

Is she hot? 👀
