Since about a year and a half ago, I have been in a relationship with someone who is an ex-colleague. At first as it was private, I only told my close friends at work. Eventually my boss came to know about our relationship. Since then, I feel like she's always trying to get involved in our life. As a matter of fact, my fiancé worked under her supervision some years ago so they know each other.
As we work together everyday, quite often, we usually take our tea break together to discuss work or other matters. But since she found out about us, she is now always asking personal questions concerning us. Questions about what we did this weekend, when we are meeting, our plans and also our family matters. In certain ways she is acting like she knows him much better than I know him. Sometimes these conversations impact my relationship with my fiancé. In fact, we are both annoyed by the way she interferes between us.
My fiancé has told me to tell her not to interfere with us. I am quite confused what to do with this situation. I feel I might be a bit 'blacklisted' and also I respect her for she is very close to me and I see her more as a mother.
I do my best to avoid these conversations with her but sometimes it just not possible.
How can I prevent my boss from interfering in my private life in a way that preserves my relationship with my boss?
