I've been invited to a close colleague's wedding. We've worked together for many years and been through thick and thin together. I have supported her career during change and layoffs and guided her to opportunities outside of the normal career progression. Similarly, she has witnessed my difficult divorce and seen me try to rebuild my life with two young kids and a new partner. AIBU to be sad and disappointed that she has not included my partner of four years as a plus one? Maybe it doesn't help that last year my partner's colleague in a similar position invited us both to his wedding.
