I'm looking for some input, wondering if I'm being insensitive. Background, my nesting partner Ash and I didn't do a good job of "the most skipped step" so there have been some challenges in feeling secure as we date independently. My nesting partner Ash planned an overnight trip to go visit their kiddo in the next state over from us, and my partner Spruce is going to come out to see me and spend the night, partially at Ash's suggestion. While packing up were saying they were going to miss me. I responded that I was excited for them to have a good trip (I really am!) and was excited for them to come home to me. They expressed feeling hurt that I wasn't going to feel specifically missing them. The feeling I'm having is not that I'm going to be melancholy Ash is gone, just looking forward to reuniting when they return. Am I being insensitive by not just expressing the words/sentiments that Ash is looking for?

PS The Most Skipped Step (or info like it) really should be mandatory reading for both people new to poly and people who are beginning to date outside of a nesting relationship after a long time. When Ash and I started dating, we were both seeing other people but when all those relationships collapsed we didn't bother continuing to date but also didn't maintain a lot of independent connections outside of our relationship. I think of the challenges we've faced dating outside nesting relationship again, I think a lot of them come down to that.
