Context
I work for a global tech company as an engineer. I was working in the UK up until very recently until I moved (with the company) to the Netherlands. Both countries are very tolerant to the LGBT community. However, we also operate in countries that are less tolerant (such as areas of the US). I don't make an effort to hide - if someone asks, I'll usually say. The same with people asking about boyfriends and so on - I'll just correct and move on. No big deal.
Problem
The situation is that my boss feels it is appropriate to out me as gay to anyone she meets in the company. This has been via email, weekly stand-ups etc. I've brought it up with her before, trying to explain that I am not comfortable with this. In particular, I am not happy that she is outing me to our US colleagues. It is also not her business and frankly, I'm astounded that she feels it appropriate to share this. I purposefully did not tell her for a long time and would dodge any questions she asked.
I am not sure what to do here.
I am hesitant on involving HR at this point, especially after moving to a new office (this involved signing a new contract - I have no probationary period on this contract and have a continued service clause).
I have tried to subtly bring it up to her that I am not comfortable with this but she says that she doesn't even consider it to be an issue as 'she is so okay with it'.
How can I get my boss to stop outing me to colleagues and understand why this is a problem for me? Any guidance would be great here as I am not sure what to do, and am not sure if this is a legal issue or not (especially as I have moved country during this time).
