OA lang ba ako pero parang pinapa overthink ako ng boss ko about my relationship?

OA lang ba ako pero parang sinisiraan ng boss ko yung bf ko or pinapa overthink ako na baka madaming gf yung bf ko dahil seaman. Alam ng boss ko na I had premarital sex me with my bf and she keeps saying na ano daw assurance ko na yung bf ko yung makakatuloyan ko, bakit daw ako nagpapadala sakanya. Tbh, I don’t get her, sguro hindi sya masaya sa relasyon nya. I just keep quiet when she’s saying this because I don’t want to waste my energy explaining to her my relationship dynamics since I’m on my last week working with her. She did not even understand na ginusto ko naman yung nangyari, for godsake I’m 26(F) already, she just had this impression in her head na uto-uto ako and I’m stupid and immature.
