So an ex colleague invited me to her wedding, she gave me a wedding invite (it’s next year). We were colleagues for few years, no friends in common, maybe saw each other few times outside of work but that’s it, we weren’t besties. But yet gave me an invitation. I do not want to go (it would involve travel, accommodation etc) my partner has been invited and met her once and did not like her Very much. How do I politely decline???
