LOL about that article. Parts of it resonated for me, so I thought it might for you too. If you want to know the truth, my occasional invitations hurt me personally more than our R overall, I think. Showing no disappointed reaction and having alternate plans in place that H knows about relieves the pressure on him aspect, somewhat. I hope.
Don't worry about the ego pumping, if possible. You have to get your best game face on to spin the GAL on the rejection though so get ready. And then prepare to have to deal with your feelings later alone. Psyching yourself up to touch the old hot stove. LOL
