How to politely refuse an ex-boyfriend to invite him to dinner? Details, we broke up for half a year, and this year he graduated from his senior year and wrote a thesis.

Then don't go. Leave it alone. Just say something is out of stock. Don't be so entangled if you have broken up. Although people may just want to thank you. But as long as you don't want to go, you can tell him directly. There is nothing to worry about. Euphemism is the most annoying. Maybe people will think you have something in mind.
