"That's not ...." He pauses, takes a deep breath, and lets it out. "That's not entirely true. About a proper romance. It's just new to my brain but the year I got in my head, I was living with Wylan." So Jesper has been in a proper romance with a live-in boyfriend. If only it would help him navigate how romances work in general, but that was only with one person.

"And in full disclosure, Wylan's here. In Cadens. He doesn't remember any of that, he's from earlier in the timeline. We're not currently together because he's, um, struggling. With me wanting to keep my life the way it is here." AKA meaning that he doesn't want to give up his other lovers. That includes Mat, it always includes Mat, because he did think they were probably going to get back together.

He thinks it is probably smart to let Mat know that his ex is around. Communication is something they're not as good at as they should be, so he's putting into action trying to be better.

"Him being here doesn't change anything about the way I feel about you, or wanting us to be together again. I just don't want to keep secrets about something like that." This isn't just anyone showing up. It's Wylan, and he confessed that in Jesper's memory, they've been together a year.
