Before getting married I got sick of saying 'fiancé', just felt like it came across that I was trying to make sine sorry of point - which I wasn't. Suppose it didn't help that a colleague used to say "... your boyfriend, oh sorry, fiancé... " so she may have put the worry into my head. Realistically the vast majority of people do not care whether their colleague has a boyfriend, a fiancé, a husband, a hubby, a wife, a dozen cats, whatever.
