You're right, emotional context is important. In Jean's case, she recently reconnected with Scott. While they confronted many of their issues during their time-displacement, they haven't exactly made it clear where their relationship stands now. And Jean has very good reason to consider this marriage an "open marriage," though I am not saying that she does or would.
If my assumption turns out to be true, and Jean and Scott are the mainstays of X-Men, it is my hope that Duggan will begin to explore and, as a result, more clearly define their relationship.
