I am writing down the main parts of the dream that I do remember almost two days after, therefore not much detail.
I was walking with df and other friends on the way to some kind of dinner. Df n I weren’t “together” but we did walk beside each other and sat next to each other as well at the round table. We barely talked to one another because we were both very engaged in the group conversation.
I looked over a few seats down the table and noticed ex husband sitting there as well, not participating and kind of skulking. I figured roommate must’ve invited him which was fine, it wasn’t my party. It was just a shame to see him NOT enjoying his time out in the least bit just because he saw that df and I are friends.
