We organised dinner with my work colleagues and their wives 6 weeks ago. Colleagues been asking for years I've avoided as DH is not the easiest wanted to avoid a scene with people I need to get along with. Finally gave in thinking maybe it will be fun surely I can trust DH for one night... so he's fallen out with me and now threatening to pull out. Have a sitter, don't want to look like an idiot at work can't he just put all this stuff aside and realise I need him to make a good impression for me?
